I had better luck losing to him. I used a farming deck that is a reliable 7-8 k and I can't get crap. I lose horribly against him and he drops D-Hero Dasher.
In terms of the common skills, his droprate is crazy for me. One time, he gave me Draw Sense Dark two times in a row. And don't even get me started on those crappy LifeboostB skills. It's like he is possessed or something.
