i beat it yesterday, the gimmick is that using blizzard on the ampharos is a viable strat. the question is, who the hell thinks to use blizzard against ice-types?!
hmm, no idea than, might be the difficulty i'm playing on, her mamoswine doesn't ever get oh-ko'd unless it's a crit, even with a leveled zangoose, that and it most of the time just ice shards me and ohko's me.
