96-416: The collectible card game Magic: The Gathering published nine base sets from 1993–2007, also referred to as core sets . The base sets were considered descendants of the original Limited Edition , and shaped the default setting and feel of Magic. These sets consisted entirely of reprinted cards. These cards were generally simpler than cards in expansion sets, omitting multicolored cards, and used only
192-435: A peek operation can, without modifying the stack, return the value of the last element added. The name stack is an analogy to a set of physical items stacked one atop another, such as a stack of plates. The order in which an element added to or removed from a stack is described as last in, first out , referred to by the acronym LIFO . As with a stack of physical objects, this structure makes it easy to take an item off
288-690: A 1994 copyright date displayed at the bottom, along with the artist credit. Booster packs look identical to normal Revised Edition packs, and as such, telling them apart is impossible without opening them. No starter decks were made. Twenty Revised cards were originally in the Arabian Nights expansion, and another nineteen were originally in the Antiquities expansion. Thirty-five cards that were in Unlimited were not in Revised , including
384-544: A Roman Numeral 'V' as the expansion set. The Traditional Chinese version came out notably later than the English version, by which time Wizards of the Coast had decided the feature was necessary.) The release of Sixth Edition brought a new version of the rules. Notable changes included: Some of these changes were well-received, but the combination of all of the changes proved to be extremely controversial and divisive, and
480-551: A beveled edge which Revised cards have not. Revised Edition (also simply known as Revised ) was the sixth set and third core set released for Magic: The Gathering . Like previous core sets, it had no expansion symbol. Revised Edition cards are white-bordered and generally known for their washed-out look. The set was released in April 1994 and contained 306 cards. It was the first base set to contain cards from black-bordered sets other than Alpha and Beta . An advertisement in
576-695: A brown background to a silvery-white background, and mana symbols appearing in the text box were no longer colored. The later two changes themselves were changed shortly thereafter; in Fifth Dawn , the artifact face was darkened to be more distinguishable from white cards. In Champions of Kamigawa , Wizards restored colored mana symbols in card text boxes. Several tournament staples which had appeared in 7th Edition, including Opposition , Llanowar Elves , Counterspell , and Duress , were not present in Eighth Edition . The Circle of Protection series,
672-546: A card box wrapper featuring new art. The player's guide was also reduced in size but was now sturdier. Also added were 6 divider pieces with artwork for inside the boxes. As of 2013, Ninth Edition is the last Magic set to be printed with white borders. The set's premium foil cards were printed with black borders. Cards made available in Cyrillic when Ninth Edition was marketed in Russia also were black-bordered; this marked
768-530: A card slot in the Shards of Alara block of 2008. Revised was the first base edition of the game to be sold in multiple languages. Black bordered, limited editions were produced in French, German, and Italian. Unlimited, white bordered editions in the same languages were produced after the limited editions had sold out. One card-printing error of note appeared on the card Serendib Efreet . This blue creature card
864-544: A character) as taking their arguments from the stack, and placing any return values back on the stack. For example, PostScript has a return stack and an operand stack, and also has a graphics state stack and a dictionary stack. Many virtual machines are also stack-oriented, including the p-code machine and the Java Virtual Machine . Almost all calling conventions —the ways in which subroutines receive their parameters and return results—use
960-488: A common stack to store both data local to a called procedure and the linking information that allows the procedure to return to its caller. This means that the program moves data into and out of the same stack that contains critical return addresses for the procedure calls. If data is moved to the wrong location on the stack, or an oversized data item is moved to a stack location that is not large enough to contain it, return information for procedure calls may be corrupted, causing
1056-635: A dedicated register for use as the call stack stack pointer with dedicated call, return, push, and pop instructions that implicitly update the dedicated register, thus increasing code density. Some CISC processors, like the PDP-11 and the 68000 , also have special addressing modes for implementation of stacks , typically with a semi-dedicated stack pointer as well (such as A7 in the 68000). In contrast, most RISC CPU designs do not have dedicated stack instructions and therefore most, if not all, registers may be used as stack pointers as needed. Some machines use

#17327802431331152-426: A destination. If random paths must be chosen, then after following an incorrect path, there must be a method by which to return to the beginning of that path. This can be achieved through the use of stacks, as a last correct point can be pushed onto the stack, and popped from the stack in case of an incorrect path. The prototypical example of a backtracking algorithm is depth-first search , which finds all vertices of
1248-587: A first for a Magic set in Japanese , traditional Chinese , Korean , Spanish , and Portuguese , which was printed primarily for the Brazilian market. Korean and Chinese Fourth Edition cards have been made with black borders, Japanese, Portuguese, and Spanish cards exist with white and black borders. Fourth Edition included the beveled border missing from the previous core set, Revised . The colors were also much more saturated than in Revised . This set
1344-404: A fixed location in memory at which it begins. As data items are added to the stack, the stack pointer is displaced to indicate the current extent of the stack, which expands away from the origin. Stack pointers may point to the origin of a stack or to a limited range of addresses above or below the origin (depending on the direction in which the stack grows); however, the stack pointer cannot cross
1440-479: A graph that can be reached from a specified starting vertex. Other applications of backtracking involve searching through spaces that represent potential solutions to an optimization problem. Branch and bound is a technique for performing such backtracking searches without exhaustively searching all of the potential solutions in such a space. A number of programming languages are stack-oriented , meaning they define most basic operations (adding two numbers, printing
1536-470: A little bit too good, but not quite so powerful as to heavily disrupt tournaments, including Lightning Bolt , Swords to Plowshares , and Serra Angel . Many of these cards were brought back in later sets after the designers had re-evaluated their impact on play. A few cards that were in Revised but had been cut from Fourth were brought back as well. Fifth Edition also set a new precedent by changing
1632-467: A loose story. Eighth Edition , also known as Core Set , was a Magic: The Gathering set released on July 28, 2003. Its expansion symbol is the number 8 with 3 cards behind it. Eighth Edition was released to coincide with the 10th anniversary of the original release of Magic . Every previous expansion had at least one card reprinted in Eighth that had not been reprinted in the base set before, with
1728-425: A new item is pushed onto the stack; if it points to the next available location in the stack, it will be updated after the new item is pushed onto the stack. Popping the stack is simply the inverse of pushing. The topmost item in the stack is removed and the stack pointer is updated, in the opposite order of that used in the push operation. Many CISC -type CPU designs, including the x86 , Z80 and 6502 , have
1824-464: A number of problems with the Limited Edition and Unlimited Edition rules. Two changes had a large effect on game play. First, the rule that "multiple effects resolve simultaneously unless a conflict arises" was changed to "effects always resolve last-in-first-out ". The concept was later refined and then referred to as the "stack", an idea taken from computer programing's stack . Second,
1920-518: A perennial core set entity, remained in the set but changed from common to uncommon. A number of simple cards, such as Vizzerdrix , were reprinted only for products directed at new players and were not present in booster packs. Ninth Edition was a Magic set released on July 29, 2005. It continued Eighth Edition' s terminology change of referring to itself as a core set. Ninth Edition contained 350 cards available in booster packs, all reprints from earlier Magic sets. Similar to Eight Edition ,

Following is an example program in Java language, using that class. A common use of stacks at the architecture level is as a means of allocating and accessing memory. A typical stack is an area of computer memory with a fixed origin and

#17327802431332112-517: A series of votes on the Wizards website deciding what got reprinted. Eighth was also the first base set with a promotional card given to players who played in a prerelease tournament. Eighth features many cards from older base sets and expansions. While many of these cards were powerful during their original print run, on the whole they were not perceived as measuring up to the power in Standard at
2208-413: A special case of a list. In either case, what identifies the data structure as a stack is not the implementation but the interface: the user is only allowed to pop or push items onto the array or linked list, with few other helper operations. The following will demonstrate both implementations using pseudocode . An array can be used to implement a (bounded) stack, as follows. The first element, usually at
2304-434: A special stack (the " call stack ") to hold information about procedure/function calling and nesting in order to switch to the context of the called function and restore to the caller function when the calling finishes. The functions follow a runtime protocol between caller and callee to save arguments and return value on the stack. Stacks are an important way of supporting nested or recursive function calls. This type of stack
2400-455: A specific type of data that can be provided to such a program such that the return address of the current procedure is reset to point to an area within the stack itself (and within the data provided by the attacker), which in turn contains instructions that carry out unauthorized operations. This type of attack is a variation on the buffer overflow attack and is an extremely frequent source of security breaches in software, mainly because some of
2496-503: A stack for arithmetic and logical operations; operands are pushed onto the stack, and arithmetic and logical operations act on the top one or more items on the stack, popping them off the stack and pushing the result onto the stack. Machines that function in this fashion are called stack machines . A number of mainframes and minicomputers were stack machines, the most famous being the Burroughs large systems . Other examples include
2592-417: A stack. Many compilers use a stack to parse syntax before translation into low-level code. Most programming languages are context-free languages , allowing them to be parsed with stack-based machines. Another important application of stacks is backtracking . An illustration of this is the simple example of finding the correct path in a maze that contains a series of points, a starting point, several paths and
2688-549: A two-level stack had already been implemented in Konrad Zuse 's Z4 in 1945. Klaus Samelson and Friedrich L. Bauer of Technical University Munich proposed the idea of a stack called Operationskeller ("operational cellar") in 1955 and filed a patent in 1957. In March 1988, by which time Samelson was deceased, Bauer received the IEEE Computer Pioneer Award for the invention of
2784-412: A variable size. Initially the size of the stack is zero. A stack pointer (usually in the form of a processor register ) points to the most recently referenced location on the stack; when the stack has a size of zero, the stack pointer points to the origin of the stack. The two operations applicable to all stacks are: There are many variations on the basic principle of stack operations. Every stack has
2880-465: Is also the first set to be printed using the new template for enchantments. Previously, enchantments that were played on other permanents were called "local enchantments" and were printed with the type "Enchant creature", "Enchant land", etc. With the Champions of Kamigawa set, Wizards of the Coast made an effort to simplify the type line, which had contained rules interactions that were not written on
2976-437: Is used implicitly by the compiler to support CALL and RETURN statements (or their equivalents) and is not manipulated directly by the programmer. Some programming languages use the stack to store data that is local to a procedure. Space for local data items is allocated from the stack when the procedure is entered, and is deallocated when the procedure exits. The C programming language is typically implemented in this way.

The "top" and "bottom" nomenclature is used irrespective of whether the stack actually grows towards higher memory addresses. Pushing an item on to the stack adjusts the stack pointer by the size of the item (either decrementing or incrementing, depending on
3168-486: The Magic 2010 set. According to Wizards of the Coast, the previous base sets had "been completely marginalized by the enfranchised player base", and change was required to make the base sets of interest to players of all skill levels once more. Unlimited Edition , occasionally referred to as Second Edition , was the second Magic: The Gathering set and the second base set. It was released on December 1, 1993; this time
3264-557: The COP400 , implements a stack either directly in hardware or in RAM via a stack pointer, depending on the device. Many stack-based microprocessors were used to implement the programming language Forth at the microcode level. Calculators that employ reverse Polish notation use a stack structure to hold values. Expressions can be represented in prefix, postfix or infix notations and conversion from one form to another may be accomplished using
3360-497: The Ninth Edition Core Game contained 9 "starter cards", labeled with the collector numbers S1 through S10 (there is no card labeled S6, however), which were not available in booster packs. These were simple "vanilla" creatures, such as Eager Cadet , which were designed to introduce new players to the game. Ninth Edition features only mechanics present in previous expansions. However, Ninth Edition does modify
3456-540: The Power Nine . A few of the cards that were removed from the base set reappeared in later sets, such as Icy Manipulator , which would be reprinted in Ice Age . A few others would be reprinted in Eighth Edition to celebrate the game's 10th anniversary. Cards removed were generally thought to either be confusing, or to have power level issues. Notable cards include: The Fourth Edition of Magic: The Gathering
3552-443: The register file for all (two or three) operands. A stack structure also makes superscalar implementations with register renaming (for speculative execution ) somewhat more complex to implement, although it is still feasible, as exemplified by modern x87 implementations. Sun SPARC , AMD Am29000 , and Intel i960 are all examples of architectures that use register windows within a register-stack as another strategy to avoid
3648-406: The zero offset , is the bottom, resulting in array[0] being the first element pushed onto the stack and the last element popped off. The program must keep track of the size (length) of the stack, using a variable top that records the number of items pushed so far, therefore pointing to the place in the array where the next element is to be inserted (assuming a zero-based index convention). Thus,
3744-524: The "old rules". The rules were drastically changed in Sixth Edition . Sixth Edition , also known as Classic , was released on April 27, 1999. It contains 350 cards including both reprints of cards from previous core sets as well as new reprints from expansion sets through the Weatherlight expansion. The name "Classic" was prominently featured on cases of packs of the set, and the set
3840-626: The CISC HP 3000 machines and the CISC machines from Tandem Computers . The x87 floating point architecture is an example of a set of registers organised as a stack where direct access to individual registers (relative to the current top) is also possible. Having the top-of-stack as an implicit argument allows for a small machine code footprint with a good usage of bus bandwidth and code caches , but it also prevents some types of optimizations possible on processors permitting random access to

Also removed were the original ten "dual lands" (one for each pair of Magic's five colors ). With the ability to tap for one mana of either of two colors, they were deemed too powerful. A number of other cards would also be pruned from the set for being too powerful, but some (such as Clone ) would appear in future sets. Wizards has used Cartamundi as their card printer since Alpha . For some undocumented reason, during

The beveling was returned in 4th Edition , and the colors were much more vibrant in that set. The large print run meant that Revised basic lands were so numerous and common that it was uncommon to find any other lands in decks until several years later. The collation of
4416-588: The biggest cosmetic change to the base set, however, was the expansion symbol. Sixth Edition was the first core set to have an expansion symbol, which was necessary to show the cards' rarities (another practice that originated in Exodus ). The set's expansion symbol was the Roman numeral VI, or 6. (This change had occurred slightly earlier in the Traditional Chinese version of Fifth Edition , which used
4512-445: The booster packs. Starter packs were also improved, with mana symbols replacing the simple colored dots present on the card back. Finally, an overall red-brown theme was given to the packaging, which would persist for Fifth Edition before changing to green in 6th Edition . Starter decks in this set included an additional rare, bringing the total to three. However, the starter decks contained fewer uncommons, going down to nine from

Errata was issued to make all such cards conform to this template, and Ninth Edition became the first set where the cards were actually printed with this changed wording. With Ninth Edition came a redesign of Fat Packs , special products that came with an array of both booster packs and side Magic items such as life counters. The Fat Pack consisted of two boxes wrapped around by
4704-505: The cards already. Seventh Edition , released in 2001, was sold both as a "Basic" and an "Advanced" product, with the expansion sets of the time marked as "Expert". Eighth and Ninth editions were marketed similarly. However, sales were disappointing, an alarming problem for Wizards, as some entry point for newer players was required to keep Magic alive. In 2009, Wizards of the Coast changed their policy for base sets, and began making smaller base sets that included new cards, starting with
4800-413: The cards made it possible for a basic land card to appear in the common and uncommon slots of a pack. This was intentional; the land cards were printed on the common and uncommon print sheets. Basic lands would get their own full print sheets in 4th Edition , making Revised the last tournament-legal set until Seventh Edition in which basic lands could be found in booster packs. Basic lands returned as
4896-665: The chance to manage a part of the set's brand. The results gave the Roman numeral "X" over the number "10", along with many other card, art, and flavor text choices. Tenth Edition was the first core set since Beta to be printed with black-bordered cards, rather than white-bordered ones. Tenth Edition is also the first core set to include legendary creatures (two of each color), bringing back flavorful relics of Magic's past such as Squee, Goblin Nabob , and Kamahl, Pit Fighter .

However, the cards were far paler than their Unlimited counterparts, and the three-dimensional beveling of the cards was cropped out. The omission of

It is estimated that about 500 million cards of the set were produced, which fully eliminated

Tenth Edition was a Magic set released on July 13, 2007, replacing Ninth Edition as the core set of cards for standard tournament play. The symbol for Tenth Edition is the Roman numeral "X". As part of their "Selecting Tenth Edition " promotion, Wizards of the Coast gave fans
5472-536: The game's rules and card mix. The set's designers stated in The Duelist that they wanted to prune from the base set cards that were too powerful or too weak. Many overpowered cards from Limited and Unlimited Editions that had survived the past two rotations were removed from Fifth , but a handful, including Dark Ritual , still survived. Unlike its predecessors, though, Fifth Edition also removed many cards that Magic 's Design and Development team saw as just

#17327802431335952-526: The normal dot design on the back. Fifth Edition was the seventeenth Magic: The Gathering set, released in March 1997. It contained 449 cards, counting multiple illustrations of the basic lands, making it the largest card set in the game's history. It was the first edition of the core set to reprint cards from Fallen Empires , Ice Age , and Homelands . Like its predecessors, Revised and Fourth Editions, Fifth Edition made numerous changes to
6048-435: The origin of the stack. In other words, if the origin of the stack is at address 1000 and the stack grows downwards (towards addresses 999, 998, and so on), the stack pointer must never be incremented beyond 1000 (to 1001 or beyond). If a pop operation on the stack causes the stack pointer to move past the origin of the stack, a stack underflow occurs. If a push operation causes the stack pointer to increment or decrement beyond
6144-461: The original abilities and keywords of Magic such as Flying and Trample . This simplicity led to many cards from these sets being considered "staples" of deck design. All cards were given a white border to mark them as reprints, with a few exceptions ( Tenth Edition , foil cards in Seventh - Ninth Editions). From Fourth Edition in 1995 onward, a new base set would come out once per two years in

Fourth Edition lands were only available in starter decks. The change

Some cards were printed by the United States Playing Card Corporation, and had a thicker stock along with a glossy overcoat on the back.

Malicious parties may attempt a stack smashing attack that takes advantage of this type of implementation by providing oversized data input to a program that does not check the length of input.

Unlimited cards have white borders rather than black, however.

If the stack is empty, an underflow condition will occur upon execution of either the "stack top" or "pop" operations. Additionally, many implementations provide a check if the stack is empty and an operation that returns its size. A stack can be easily implemented either through an array or a linked list , as it is merely
6912-682: The same stack for both data and procedure calls has important security implications ( see below ) of which a programmer must be aware in order to avoid introducing serious security bugs into a program. Several algorithms use a stack (separate from the usual function call stack of most programming languages) as the principal data structure with which they organize their information. These include: Some computing environments use stacks in ways that may make them vulnerable to security breaches and attacks. Programmers working in such environments must take special care to avoid such pitfalls in these implementations. As an example, some programming languages use

On the secondary market it sells for thousands of dollars. The print run was recalled and destroyed; however, about 40 booster boxes that were shipped to England and Tennessee survived. No more than 11 or 12 of each rare exists. This print run is known primarily for its extremely scarce and valuable cards and packs. Cards are distinguished by dark coloring and

Early in the history of Magic , the sets sold out nearly instantaneously, and supplying the game's growing fan base proved tricky. Sales were also concentrated on the West Coast of the United States, where Wizards of the Coast was based. The earliest base sets— Unlimited , Revised , and Fourth Edition —helped provide
7200-433: The stack is simply the size of the dynamic array, which is a very efficient implementation of a stack since adding items to or removing items from the end of a dynamic array requires amortized O(1) time. Another option for implementing stacks is to use a singly linked list . A stack is then a pointer to the "head" of the list, with perhaps a counter to keep track of the size of the list: Pushing and popping items happens at
7296-425: The stack itself can be effectively implemented as a three-element structure: The push operation adds an element and increments the top index, after checking for overflow: Similarly, pop decrements the top index after checking for underflow, and returns the item that was previously the top one: Using a dynamic array , it is possible to implement a stack that can grow or shrink as much as needed. The size of

Similar concepts were independently developed by Charles Leonard Hamblin in the first half of 1954 and by Wilhelm Kämmerer [ de ] with his automatisches Gedächtnis ("automatic memory") in 1958. Stacks are often described using the analogy of a spring-loaded stack of plates in a cafeteria. Clean plates are placed on top of the stack, pushing down any plates already there. When
7488-417: The stack to be in a fixed position. The illustration in this section is an example of a top-to-bottom growth visualization: the top (28) is the stack "bottom", since the stack "top" (9) is where items are pushed or popped from. A right rotate will move the first element to the third position, the second to the first and the third to the second. Here are two equivalent visualizations of this process: A stack
7584-468: The summer of 1994. This print run intended to fix some of the errors with Revised , including the washed-out color, but had problems of its own. The colors were considered too dark and the artist credited for Plateau stayed uncorrected as well as the artist credited for Serendib Efreet, although the Efreet had received its original color and art again. A new misprint occurred with the green card Hurricane ;
7680-451: The time, known for "Affinity" decks powered by cards from the Mirrodin block. Thus, few cards in Eighth Edition saw tournament play. A new card face was introduced in Eighth Edition . The colored frames around the edges of the card were redesigned and narrowed, boxes were placed around card names and creatures' power and toughness, card names were printed in a new font (Matrix Bold, rather than Goudy Medieval ), artifacts switched from
7776-441: The top element. A stack may be implemented to have a bounded capacity. If the stack is full and does not contain enough space to accept another element, the stack is in a state of stack overflow . A stack is needed to implement depth-first search . Stacks entered the computer science literature in 1946, when Alan Turing used the terms "bury" and "unbury" as a means of calling and returning from subroutines. Subroutines and
7872-402: The top of the stack, but accessing a datum deeper in the stack may require removing multiple other items first. Considered a sequential collection, a stack has one end which is the only position at which the push and pop operations may occur, the top of the stack, and is fixed at the other end, the bottom . A stack may be implemented as, for example, a singly linked list with a pointer to
7968-413: The top plate is removed from the stack, the one below it is elevated to become the new top plate. In many implementations, a stack has more operations than the essential "push" and "pop" operations. An example of a non-essential operation is "top of stack", or "peek", which observes the top element without removing it from the stack. Since this can be broken down into a "pop" followed by a "push" to return
8064-649: The use of slow main memory for function arguments and return values. There is also a number of small microprocessors that implement a stack directly in hardware, and some microcontrollers have a fixed-depth stack that is not directly accessible. Examples are the PIC microcontrollers , the Computer Cowboys MuP21 , the Harris RTX line, and the Novix NC4016 . At least one microcontroller family,
8160-487: Was a stylized 7. Despite being an "Advanced" level set, Seventh Edition contained a separate basic subset for new players similar to the products that were previously offered as Starter 2000 . Cards that appeared in the Seventh Edition Starter special pre-constructed theme decks did not appear in boosters. This would be the last starter level product released by Wizards of the Coast. Seventh Edition
8256-475: Was also the first core set to include a Wizards of the Coast copyright notice at the bottom of the card, in addition to the standard illustration credit. Booster packs , for the first time in a core set, came in packs with cropped card art on the packaging. Up to this point, Alpha , Beta , Unlimited , and Revised all had a common-looking booster pack packaging. The cards Brass Man, Hurloon Minotaur, Mana Vault, Mesa Pegasus, and Spirit Link were shown on
8352-621: Was compared to the Portal set and rules. The state of the game prior to these changes was often referred to as "real Magic" by people who hated the changes, a fact that Wizards of the coast eventually acknowledged on the "Old Fogey" card from the Unhinged expansion. Seventh Edition was a Magic: The Gathering set released on April 2, 2001. It is the only core set since the original Limited Edition to have introduced all-new art for every card. The set contained 350 cards. The expansion symbol
8448-463: Was later considered so overpowered as to merit banning from a number of sanctioned tournament formats. Fifth Edition was the first version of the base set to use the cosmetic changes that were introduced in the Mirage expansion (including a slightly expanded text box and bolder, more visible power/toughness numbers) It was also the last version of the base set to use what are sometimes referred to as
8544-516: Was misprinted with a green border and a picture of another card, Ifh-Bíff Efreet . The name, mana cost and rules text were all correct, though. The Revised version is now the most common due to the limited print run of the original, intended versions. The card Disintegrate was missing the clause "and cannot be regenerated". The card Onulet incorrectly listed the artist as Kerstin Kaman instead of Anson Maddocks. The printing of Revised cleared up
8640-423: Was mostly seen as a positive, since by this time lands were ubiquitous and players were unhappy to find a land in place of a "real" card. Fourth Edition introduced the modern turned arrow tapped symbol, replacing the rotated "T" that had been introduced in Revised , as a universal tap symbol to include on cards in all language editions of the game. This symbol was first used in an expansion with Ice Age , which
8736-552: Was referred to by both titles by both Wizards of the Coast and players. Sixth Edition was the first base set to have its artist information centered on the card (a printing practice started in Exodus ). It was also the first base set to have collectors' numbers (which also originated in Exodus ). The rules text on basic lands was also replaced with just a mana symbol, as featured in the Portal starter sets of 1997 and 1998. Perhaps
8832-594: Was released in the summer. Current cards still use the turned arrow, albeit with a slightly different illustration. Like the previous core set and all core sets since, several cards were removed and new ones were added from Fourth Edition . Among those cards removed were those that had attracted controversy from those outside the game. Most of the cards whose art depicted nude or near-nude humanoid forms (including Earthbind and Guardian Angel ) were excised, as were many that had overtly religious themes (including Resurrection and Demonic Hordes ), though one demon, Lord of
8928-444: Was the first set to be officially titled as something other than just Magic: The Gathering . The "Unlimited Edition" label appears on the booster boxes, decks, and booster packs. While it is possible to distinguish Unlimited cards from Revised cards by just looking at the text (wording and type set) the cards from both sets are more easily distinguished by comparing the borders of the cards. The picture frame of Unlimited cards has
9024-594: Was the first version of the base set to reprint cards from the Fallen Empires and Homelands expansion sets; it also reprinted more cards from those sets than any other version of the base set has. Because those expansion sets were perceived by some players as weak, there was some dissatisfaction with the Fifth Edition card mix. However, many of the reprinted cards were good enough to be used in tournaments, and at least one Ice Age card, Necropotence ,
9120-479: Was the last base set printed in the 'old' frame; Eighth Edition introduced the modern card frame. Seventh was the first base set to contain foil cards, which were printed with black borders. It was the last base set to be released prior to the final expansion of the then-current block ( Seventh Edition was released before Apocalypse ). Starting with Eighth Edition , the base set editions (which, with 8th, would become known as Core Set editions) were released after
9216-543: Was the tenth set released for the game, and the fourth base set. The set was released in April 1995 and contained 378 cards. It was the first set to reprint cards from the expansions Legends and The Dark . Fourth Edition cards have white borders. The set has no expansion symbol. Fourth Edition was the first Magic set to be printed in Asian languages. It was published in English , French , German , Italian , and as
