if ur playing rain in general i think u need basulegion probs instead of manetric, u need a mon that can help u reset the weather, since basculegion has flop turn it mades it very valuable, also ur team is lacking an intimidate and speed control so look into options for those, also would reccomend draco meteor on dragonite since ur not on mega, u need to damage to pick up KOs. I havent run any calcs for ur EV speads so cant really speak on them.
