Dance of the Skywise

A combat trick disguised as a transformation, and the instant-speed window is the whole point. You hold up two mana, let the opponent commit to a block or an attack, then flatten your creature into a uniform 4/4 flier mid-combat. Setting base power and toughness to a flat 4/4 is what makes it a trick worth running: a modest ground body suddenly hits for four in the air and connects where it could not before, or trades up against an attacker it had no business eating. Losing all abilities is the genuine wrinkle, though not as protection: it strips drawbacks. A creature saddled with "can't block," a downside keyword, or a tap-to-survive cost sheds all of it the moment it becomes a blue Dragon Illusion, and its printed stats stop mattering entirely. The Illusion type is window dressing; the granted flying is not, and that evasion is what turns a board of small ground threats into a finisher assembled at the last possible moment. What you pay for all this is impermanence: the creature reverts the instant the turn ends, so the card buys exactly one window. One alpha strike from the air, one surprise blocker that survives, one ground-bound threat that briefly outclasses what was sent to deal with it. It rewards holding mana and reading the opponent's line rather than developing the board, the blue way to win a creature fight without committing a creature to it.
