Some nice fellow wonder traded me an Adamant Mawile with perfect IVs in HP, Attack, and Speed. I just finished EV training for attack, but I'm not sure what I should run as the second one. A few pages I've seen focus on defense, but it has max IVs in HP and Speed so I think it would be better to do one of those. But I'm not very into competitive battling, so I don't really know best. Where should the rest of my EVs go?
