Unglued

Free-for-All

When Free-for-All comes into play, set aside all creatures in play, face down.
During each player's upkeep, that player chooses a creature card at random from those set aside in this way and puts that creature into play under his or her control.
If Free-for-All leaves play, put each creature still set aside this way into its owner's graveyard.

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.
