We couldn't really say anything before it was announced, but the Penny Arcade card game from Sabertoof is a part of their "Universal Fighting System," a term which probably didn't make any sense. Well, they just announced their Soul Calibur set, so now you have a better idea what they're going for. Every set is mechanically compatible, so Gabe fighting Mitsurugi (or whatever) is entirely possible and perhaps even encouraged. Even if the idea of a PA set didn't turn your crank, there's probably some SC enthusiasts who might "dig" it.
