Since cards must be deployed in numbered order, it takes real strategy to design a good deck and deploy cards effectively. Slot one allows attack by Magic, Chaos or Melee monsters, while slots two and three allow for Magic, Chaos or Ranged attackers. You can place any monster you want to in any slot, but the slots only allow specific monsters to attack from them. Players must place cards in numbered order.
There are three slots where players can deploy Monsters which are labeled with number one (center), two (left) and three (right). Monsters come in one of four attack styles: Magic, Melee, Ranged and Chaos. Each have items that correspond in color and attack style. Card Monsters come in six different colors and 4 different attack styles.
