With a bit more polished play there I think Nick coulda won both those games :O
Game 1 sure, but I don't think I agree on game 2 since he doesn't have a good way to deal with Sceptile. If he tries to keep Flareon alive by using Flare Blitz instead of Superpower than he dies to recoil anyways. I don't quite think it's impossible, but at least I don't think Nick was in an advantageous position at any point during game 2.
Perhaps, I guess I've never ever really been impressed by Mega Scept ---
