During a recent toy show held in Japan, Konami unveiled its latest card game for the DS. Complete with card reader, this is not to be confused with the upcoming Marvel Vs. game for the DS, PSP and PC (although, how cool would that be if it were?!). Apparently, the player mixes card-playing outside of the DS with gameplay through the handheld system, which sounds a bit complicated to us. Who knows though, this could be fun, right?
