Fire Juggler

Whenever this creature becomes blocked, clash with an opponent. If you win, this creature deals 4 damage to each creature blocking it. (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.)
