Tiamat, Chromatic Queen

Flying, vigilance, deathtouch, haste, trample
When Tiamat enters the battlefield, each
opponent creates a 1/4 white Cleric, a 3/2 black
Rogue, a 4/1 red Warrior, and a 2/3 blue Wizard creature tokens.
Whenever Tiamat deals combat damage, if the defending player's party is empty, that player
loses the game.
