Stickers are an Unfinity mechanic involving separate sticker sheets containing name, art, ability, and power/toughness stickers. Effects can place those stickers on cards, where they modify characteristics according to the kind of sticker used.
Ticket counters originally served as the resource for ability and power/toughness stickers, while cards such as Wicker Picker reduced sticker costs. Sticker decks occupy one of Magic's stranger design corners and have format-specific legality concerns.
