Veiling Oddity

Creature - Illusion 2/3, 3U (4)
Suspend 4-{1}{U} (Rather than play this card from your hand, you may pay {1}{U} and remove it from the game with four time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, play it without paying its mana cost. It has haste.)
When the last time counter is removed from Veiling Oddity while it's removed from the game, creatures are unblockable this turn.¹
Illus. Dave DeVries
