Whenever you clash, tap target creature an opponent controls. If you won, that creature doesn't untap during its controller's next untap step. (This ability triggers after the clash ends.)

Prevent all combat damage that would be dealt this turn. Clash with an opponent. If you win, creatures that player controls don't untap during the player's next untap step. (Each clashing player reveals the top card of their library, then puts that card on the top or bottom. A player wins if their card had a higher mana value.)
