Tap target creature an opponent controls. That creature doesn't untap during its controller's next untap step. Cipher (Then you may exile this spell card encoded on a creature you control. Whenever that creature deals combat damage to a player, its controller may cast a copy of the encoded card without paying its mana cost.)
