Expose the Culprit (Murders at Karlov Manor 307) - Uncommon Magic: The Gathering Card

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 . Turn it face up any time for its mana cost if it's a creature card.)
