From the back of the box:Tempest of the Gods is a collectible card game based on the fantastic struggle of the gods to rule all existence. Each player rules over his or her own pantheon, pooling the faith of their devoted followers and priests to summon great champions, bring to pass cataclysmic miracles, and create all-powerful relics. The game is won when a player utterly vanquishes all opponents' cards or when a deity is summoned into play. - BoardGameGeek
