Making Chaos Magic Tournament-Legal

Since Chaos Magic is the greatest Magic format ever, I easily got eight people ready to rock and roll with a huge game of Chaos that lasted about three hours. (In the end, I managed to get a Masticore and eighty-two mana, kill a player, force two more to concede, and then die to decking, letting me come in second place.) Afterwards, several players were clambering for another Chaos game – but the more experienced players reminded them that there was no way we could play one in the forty minutes left before the store closed. However, the great interest in playing multiplayer showed by many of the Casual Magic regulars got me thinking: Is there a way to make Casual Magic a Chaos format?
