Vannifar, Evolved Enigma [Murders at Karlov Manor]

At the beginning of combat on your turn, choose one —


• Cloak a card from your hand. (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.)

• Put a +1/+1 counter on each colorless creature you control.
