Stratego

Manifest all permanents in play. Then, for each permanent in play, create a blue Aura token attached to that permanent with “Enchanted permanent has “When this permanent blocks or becomes blocked, turn it face up. If this card is a non-creature permanent, it becomes a 1/1 green Soldier creature with death touch until end of turn.” Rules text: Cards in play considered “Manifested” should be completely random to your opponent, and not random to you.
