Sticker

Stickers are adhesive labels that were introduced in Unfinity that allow players to modify cards to make them unique. Stickers are a play aid. You may use alternate options to represent them.
==Description==
Stickers act like counters in many senses but modify much more than simple +1/+1 or keywords. Cards instruct a player to place a sticker on a card as an effect. Players can only sticker their own nonland permanents. Some cards tell you to use a specific type of sticker while others are general.
To avoid players always choosing board-state effects, tickets are used as an economy, similar to energy. Most cards that allow players to sticker provide tickets. Name and art stickers have no board impact unless a card refers to the name or art, so these have no ticket cost. Ability and power/toughness stickers require a minimum of 2 tickets and max out at 6 tickets in Unfinity. When told to place a sticker, the player may opt not to spend any and preserve them for the future.
===Sticker types===
There are 48 sticker sheets in Unfinity. The adhesive used on the stickers won’t damage the card and can be reused. 1 sticker sheet appears in each booster pack, replacing a common card.
There are four types of stickers:
*Name stickers (3 per sticker sheet)
*Art stickers (3 per sticker sheet) of things you can get in the park. About two-thirds (32 of 48) of Unfinity sheets give access to a hat.
*Ability stickers (2 per sticker sheet) 
*Power/Toughness stickers (2 per sticker sheet) 
Only power and toughness stickers repeat. Each sticker sheet has three name stickers, three art stickers, two ability stickers, and two power/toughness stickers. There are 96 slots for each sticker type. 
The back of the sticker sheet is the rules sheet for stickers (same back for all the sticker sheets).
==="Stickers matter"===
Unfinity has cards that care about names and art, making those stickers mechanically relevant. Some cards care about whether or not any cards are stickered.
===Legality===
The majority of the cards that can sticker or care about stickers were eternal playable (usable in Commander, Legacy, and Vintage) at the time of their release. This was done by having "name" mechanics refer only to the name sticker, and the art stickers have no effect otherwise.
In Constructed, players had to choose ten unique sticker sheets and randomly pick three to use at the start of each game, after any sideboarding. For playing casually, there will be a tool posted online to pick three random sticker cards. If you don’t have the actual sticker sheets, you are allowed to write on slips of paper. In a booster draft, you keep and can use only the sticker sheets you open; the sticker sheets are not passed in the pack. Players of Sealed can pick three of their six sheets.
In May 2024, Wizards of the Coast reassessed the impact of stickers, and specifically , on constructed tournaments and decided that the current format meta did not match with their intentions around the design of the sticker mechanic. Originally meant as a fun Commander mechanic, tournament players were now bringing sticker decks to take advantage of the power of even if they weren't using the card themselves. This led to all cards that bring stickers into the game being banned in Pauper, Legacy, and Vintage.
===Rules===
===Rulings===
*Cards can only have one power/toughness at a time.
**If a card already has a power/toughness sticker, a player can still sticker over it with a new one, but it will replace the old one.
*Name, art, and ability stickers are additive, they don't replace or remove any existing names, art, or abilities.
**Cards that care about objects in the art still count anything “under” the sticker.
*Stickers stay on cards as they move to any public zone (stack, battlefield, graveyard, exile, ante, and command), but return to the sticker sheet if the cards they are attached to go to a hidden zone (hand or library). 
*Stickers that go back to a sticker sheet can then be used again.
*Stickers follow the same rules as counters when a permanent is being copied - they are not copied.
===Reception===
For several reasons, many players disliked stickers. The decision to allow them in eternal formats was criticized. Although the cards had been costed so that they wouldn't show up in competitive Eternal events, <c>_____ Goblin</c> was the exception, leading to an awkward porting of the card onto Magic Online that used dice-rolling instead. The sticker glue was not as resilient in practice, leading to game state problems when they were lost, which included when they fell off the sticker sheets. Furthermore, the variety of stickers plus the variety of ways to use them made a matrix that was too complex for many players. This would lead to their banning in Legacy and Vintage in May of 2024.
