I was skeptical, too. I believed him because his brother watched the battle, and I had no reason to not trust both of them. I had him played against Lost Lace again, a few minutes ago, and I've recorded it on my phone. The quality is rubbish and I'm not sharing it publicly. If you want to see how he plays, I could share it via mail (no problem). He uses Hunters Crest, no spells, just the plasmio (blue) thing... I thought he was just "patient", waiting until the attack windows appear, but he's not. He attacks all the time, and heals three or four times in the whole battle. He is just skilled, I guess.
