Unknown Phantmon

Hexproof Whenever The Unknown Phantmon deals combat damage to a player, tap the target creature that player controls. That creature doesn’t untap during its controller’s next untap step. Whenever a creature blocks The Unknown Phantmon or becomes the target of a spell or ability an opponent controls, you may exile that creature. At the beginning of each opponent’s end step, if a creature they controlled left the battlefield this turn, create a 1/1{flavor}. Your mind will betray you before I ever need to strike
