123.1 A sticker is a marker placed on an object that modifies its characteristics and/or interacts with a rule, ability, or effect. Stickers are not objects. Notably, a sticker is not a counter or a token. Changes to an object from stickers are not part of its copiable values. There are four kinds of stickers: name stickers; ability stickers; power and toughness stickers; and art stickers.
123.2 Stickers are found in boosters of the Unfinity expansion on numbered inserts. Each insert has a predetermined combination of stickers. Any rule that refers to a sticker sheet refers to the specific combination of stickers found on one of those inserts. Sticker sheets are not cards and have no characteristics. Each sticker sheet can be found at Gatherer.Wizards.com.
123.2a In constructed play, a player who chooses to play with stickers must start the game with at least ten sticker sheets selected before play begins, and each of their sticker sheets must be unique. There is no maximum number of sticker sheets a player may start the game with. Each player playing with sticker sheets reveals all of their sticker sheets and chooses three of them at random. See rule 103, “Starting the Game.”
123.2b In limited play, each player chooses up to three sticker sheets from among those in the sealed products they opened and reveals them. See rule 103, “Starting the Game.”
123.3 If an effect instructs a player to put a sticker on an object, that player chooses a sticker that is not currently on any objects they own from among the stickers they have access to and puts it on that object.
123.3a Each sticker a player has access to is discrete and is distinct from each other sticker they have access to. Two stickers are never considered to be the same sticker, even if they have the same text or information on them.
123.3c A sticker may have a ticket cost represented by a number inside a ticket symbol (see rule 107.17a). In order to put a sticker with a ticket cost on an object, the player who owns that object must pay that much {TK}. If they don’t have that much {TK}, they can’t put that sticker on an object.
123.4 Some rules and effects refer to a “stickered” object. An object is “stickered” if it currently has any kind of sticker on it. An object without any stickers on it is not a stickered object, even if it previously had stickers on it.
123.5 Stickers on an object are not retained as that object moves to a hidden zone. Stickers are retained as that object moves to a public zone and continue to apply to the new object it becomes in that zone; this is an exception to rule 400.7.
123.5a If one or more cards with stickers on them enter the battlefield as part of a melded permanent, all of those stickers are on the permanent that object becomes on the battlefield. They maintain their relative timestamp order.
123.5c If a melded or merged permanent with one or more stickers on it moves from the battlefield to another public zone, only one of the objects it becomes will retain those stickers. Its owner chooses which of the objects it becomes in its new zone retains any stickers that are on it. Effects from those stickers will continue to apply to only that object.
123.6 A name sticker consists only of one or more words. A name sticker on a permanent or on a card in a zone other than the battlefield causes the word on that sticker to be added to the text of that object’s name. This is a text-changing effect. See rule 613.1c and rule 612, “Text-Changing Effects.”
123.6a For the purposes of rules and effects related to name stickers, a “word” in an object’s name is any series of non-space characters that are separated from other non-space characters by one or more spaces. Hyphenated words and words with punctuation are considered to be one word. Blank lines, such as the one in “Wolf in ________ Clothing,” are not considered words in a card’s name.
123.6b As a name sticker is placed on an object, that object’s controller chooses a position in that object’s name for the word in the name sticker to be added, then announces that object’s new name. That word can be added at the beginning of the object’s name or after any number of the other words that are currently in its name. The new name can be further modified by other name stickers. If that object has no name, its name becomes the word added by the name sticker. Name stickers never modify or remove any of the other words in that name.
123.6c The text that a name sticker is modifying may change due to other effects and/or a permanent’s face-down status (see rule 708, “Face-Down Spells and Permanents”). To determine the name of an object with one or more name stickers, start with the object’s copiable values, then apply each name sticker’s effect and each other text-changing effect in timestamp order. The position of each name sticker will continue to be after the number of words that were before it in the object’s name when it was placed. If there are fewer words in the object’s current name, the word on that sticker is added at the end of its name instead. The position and timestamp order of each name sticker on an object is remembered as the object that sticker is on moves from one public zone to another, and it continues to apply to the new object it becomes in that zone (see rule 123.5). This is an exception to rule 400.7.
123.6d Some effects refer to the number of one or more specific letters on a name sticker. A lowercase letter and its uppercase equivalent are the same letter.
123.6e Some effects refer to the number of “unique vowels” on a name sticker. These count the number of different vowels that appear on that sticker, even if one or more of them appear more than once. The vowels are A, E, I, O, U, and Y. A lowercase letter and its uppercase equivalent are the same letter.
123.7 An ability sticker is a sticker with one or more abilities printed on it. An ability sticker on a permanent or on a card in a zone other than the battlefield causes that object to gain the ability that is printed on that sticker. See rule 613.1f.
123.7a If an effect refers to an ability of an ability sticker, it refers to the ability that sticker grants to the object it is on, even if the object it is on doesn’t currently have that ability due to another effect.
123.8 A power and toughness sticker is a sticker that has two numbers and a slash printed on it, resembling the power and toughness of a creature card. A power and toughness sticker on a creature or on a creature or Vehicle card in a zone other than the battlefield sets that object’s power and toughness to the values printed on that sticker (see rule 613.4b). If more than one power and toughness sticker is on a creature, use timestamp order to determine which one takes precedence (see rule 613.7).
123.8a An effect that refers to the power and/or toughness of a sticker refers only to the printed power and/or toughness values on a power and toughness sticker. It does not refer to any printed value on any other stickers.
