Hi, I have an Aggron, and I wanna EV train it but don't know what it EV train it in.
Its ability is Sturdy, and its nature is Docile.
The moveset I have for it is
Despite having good physical defense, Aggron isn't a reliable wall because of its bad HP and special defense and weaknesses to common attack types. The best thing you can do is give it 252 Atk/4 SpD/252 Spe so that at least it can outspeed and break slower walls.
For me I go for a toxic stall Aggron
Move Thunder Wave Toxic Curse Rest
Ev Def 248 Sp.Def 252 HP 8 I went for rock head
