Gencon saw the release of four different promotional item cards. While these cards may be included in a future set, I can't see any reason not to release them for play right now.
In keeping with the Decadence set, these cards may bear somewhat familiar names. Its been mentioned that some of these items are fairly powerful, and I suppose I tend to agree. In the right circumstances, anyway. The problem with going into a tournament is whether you want to pay for these items, knowing that they may not be valuable for you every single match. There's probably one that is, but deciding which one? That could be tricky. You can find these items Right Here.
