Nice team, you countered your rock weakness effectively. But Shuckle has too low hp to not die from a +3 waterfall from gyarados, kingdra, crawdaunt, kabutops, azumarill, Swampert, sharpedo, (etc. etc).Maybe give shuckle more defense evs instead of hp evs? This is just my opinion, you can change or keep shuckle the way it is.
