Free-for-All

When this enchantment enters, exile all creatures face down. At the beginning of each player's upkeep, that player chooses a card exiled with this enchantment at random and puts it onto the battlefield. When this enchantment leaves the battlefield, put all cards exiled with it into their owners' graveyards.
