4 or 6 players to play. Players are split into 2 teams and seated in an alternate fashion. Each team starts with a fixed number of hit points. Cards are played to attack any player of the opposing team and successful attacks result in cards drawn for the attacked player. If the hand limit of cards is surpassed, the hit points will be reduced. The attacking team also gets a crystal and crystals can be exchanged for a cup. A team wins by either collecting 5 cups or decreasing the opposing team's hit points to zero.
