As with Expanded Realms 1, Treasures and Traps: Expanded Realms 2 consists of 26 cards to be added to the T&T game deck. Each card has a unique effect, examples of which are time control spells to affect the next few rounds, poison traps, the deadly monk dojo, the surprise mimic trap, locations to power your hand and your defenses, the duel event to challenge another player, and the dimensional box to hold your goodies.
