Battle for the Ages

Creaturebound - (each player must control a creature without hexproof or shroud to cast this card). Each player chooses a creature he or she controls then sacrifices the rest.
Until end of turn each creature gains indestructible. If they do, each creature fights each other. Then the player who controls the creature with the least amount of damage dealt to it this way wins the game. If its a tie, restart the game.
