So his deck sucks, thats known. But he has two patriod cards. Its a card with a special effect of letting him peek under cards set face down. In a vs match he will use the effect every turn. What makes this obnoxious is that he will peek at the same card over and over, or if he has both of his patroids out, will flip the same card to look at TWICE. THE SAME CARD. Then the next turn he'll look at that same card AGAIN!
This apparently has horrible implications if he is on your side in a tag match, as he does the same thing about the two people kicking your ass. Wtffffffff.
One of the best card battle games out there still, but run from this guy lol.
