Expose the Culprit

Choose one or both — • Turn target face-down creature face up. • Exile any number of face-up creatures you control with disguise in a face-down pile, shuffle that pile, then cloak them. (To cloak a card, put it onto the battlefield face down as a 2/2 creature with ward {2}. Turn it face up any time for its mana cost if

it's a creature card.)
