Counter target spell unless its controller pays {X}. Clash with an opponent. If you win, that spell's controller mills four cards. (Each clashing player reveals the top card of their library, then puts that card on their choice of the top or bottom. A player wins if their card had a greater mana value.)

The opponent you clash with doesn't have to be the controller of the targeted spell.

The clash (and the result of the clash if you win) happens regardless of whether the targeted spell was countered or {X} was paid.
