[@LuckyBlackCat] At this point I'd swap him back for Furfrou. Most of the Pokemon are fine and easily explained, Munchlax was...slightly less so.

Side note: The only move Munchlax was really unable to have there was chip away, zen headbutt is an egg move. Chip away does happen to be a bit powerful due to the whole "ignore stat changes" thing that makes it almost undodgeable.
