Ya know, it really looked Duel Masters to me when I first saw it but I kind of brushed that off.
I've always been a big fan of Duel Masters, it's really too bad that it's still one of Japan's top card games, yet it's been discontinued in the US for well over 2 years now. I can't tell you tell you how much I hate Wizards of the Coast, first they try to kill Pokemon for Magic's benefit, but considering the game lived I gave them another chance when I went to play Duel Masters, but they stopped supporting that game and killed it off to better MtG after 12 sets. =/
