Octo Opus (54) [Unfinity]

When this enchantment enters, create a 4/4 blue Octopus Performer creature token named Contortionist with "At the beginning of your upkeep, you may fold this token in half." (It becomes 2/2, then 1/1, ½/½, and so on.) Sacrifice this enchantment: Draw a card and an additional card for each of Contortionist's folds.
