The first player to take all six of their prize cards is declared the winner
Fire Lord Zuko, for example, is a red-white-black creature with firebending that adds red mana whenever he attacks, and the ability to place +1/+1 counters on each creature you control when you cast a spell from exile, or whenever a permanent you control enters from exile (which is wonderfully thematic)
