characters like String and those possessed standard duelists in GX and Zexal events are obviously not going to be playable, but Antinomy most likely will be playable.
Why none loves umbra and lumis?? Imo they are quite cool and funhy. Also, masked beast deck is quite funny and enjoyable for casual duels. Not to mention it has one of the coolest summoning animations.
I love them so there's one of their players here. I asked for them even, being bummed in the first Battle City event that they were reduced to manga scans.
