Mystic Castle

Each player is a Wizard, trying to build his Mystic Castle. This consists of four towers and the four walls connecting them. You may protect your castle with soldiers, fences and crowns, and attack the other players' castles with dragons, forces, thieves, lightning bolts. Other cards (ring, amulet, sygil [sic]) protect against some attacks. The relation between the ring and dragon colours is a little convoluted, adding to the complexity a little.
