War of Supremacy is a free-for-all, king-of-the-hill style card game for 2-5 players. Players will take turns playing creature and spell cards from their hand, trying to outscore the current defender and take control of the territory. Players must master the three combat forms, find high scoring combinations in their cards, push their luck and know when to strike. If a player manages to defend a whole round against their opponents, they take the territory as a victory point and get one step closer to victory.
