You can cast this spell only if all the cards in your mana zone are fire cards. Each of your creatures in the battle zone gets "power attacker +4000" and "double breaker" until the end of the turn. (A creature that has "power attacker +4000" and "double breaker" gets +4000 power while attacking and breaks 2 shields.) "War isn't a game. Sure, one side wins, the other side loses, and it's a lot of fun, but . . . well . . . hey, maybe it is a game."
