I defeated him 2 - 0. He's a bad sport who called me a terrible duelist, and after I utterly destroyed him 2 - 0, he called me names such as "f@ggot", and called my deck lame, really mature of him.
Try to use words like "I won" instead of "destroyed" and "defeated", it's not illegal but it gives a better look. Anyway he have to confirm in this topic before we transfer DPs.
