System Gate is a living card game where two or more players race to reduce their opponent's life to zero. They do this by playing monster, spell, item and finale cards. There are three spaces on the board - left, center, and right - that monsters can be placed. If there is no monster in a player's center space, they are vulnerable to attack. Players can equip item cards to give them an edge. There are several factions, called worlds, each specializing in a unique strategy and gameplay. —description from the designer
