When duels enters the battlefield, phase out 3 creatures you control until duels leaves the battlefield. Then, an opponent does the same. After this, you each choose a creature to phase in. When a creature phased out this way dies, phase in one of those creatures. When one of you have no more creatures phased out this way, exile duels and the player who had creatures phased out this way gets 8 trophies

(any player with 25 or more trophies wins the game)
