You wont hear much from me...I dont really calculate EVs. Really all you should do is train it to lv. 100, in these pkmn games, you've pretty much one the game if you have a lv.100 pokemon
Yeah it is a good idea to train it on Hp.
But you can also Ev train it on sp.att and sp.def if you want to use it as a good sweeper.
And I am not sure if it needs to be bold like the one Expert Evan used since it doesnt really have decent defence.
sounds gd for Hp if you make it a wall as well spc def will own it will take ages to wear down that massive hp gauge but whatmove sets ae u looking at ?
