1 pokes stuck after movement sometimes and you can't use pursuit type spells after that
2 some spells do more dmg, some spells do shit ton of dmg (I think some of puruglys) and some don't do additional dmg - its weird
3 clones do not appear if you are under certain amount of hp
4 sometimes it doesn't drop enemys target on you
About some of overpowered pokemons, I'll just leave it here.
