Avoid playing duels with this guy named ooMERCENARIOoo as his gamertag on Xbox Live. I've never played with this guy before and the first time I played with him and defeated him he sent me this message: "Cancer into your family bastard". I've already written a formal complaint about this guy to Xbox Live and hope he can be banned for good. DO NOT PLAY DUELS WITH THIS GUY. He's not a normal person for sure.
