I really like the duel part of the original Orions. Its a streamlined strategy card game with five slots for cards per player, and six elements that determine what cards and spells you can play. This expansion doesnt deviate from the basic gameplay, which is good. The card game was the strongest part of the original while the campaign was the weakest.
The expansion adds more cards. It also changes several cards, removing some overpowered cards like life sacrifice and modifies some like fireball, making it more expensive and weaker at the same time. The changes do alter the nature of the duel a bit, there are more expensive cards and cards with unusual abilities like the wall cards, cards that add healing to other cards, cards that can turn cards into skeletons, modify other cards, etc. These changes deepen the strategy, although at the expense of the cheaper cards.
The duel gets some some nice options, in particular you can make custom decks, draft cards, take on challenges like only using fire/death versus life/water. I havent tried multiplayer, however. All in all its a great expansion; one that Ive been waiting for for a long time.
