I just beat the elite 4 multiple times. However, I do it different. I only use 1 pokemon to battle them. I always start with the elite member that I have a type advantage over. I usually start this at level 70.
Wow, that would really help out my team. I would get them myself, but ti would take a while. So how do you train your Pkmn? Do you battle tons in the Elite 4 or do you crunch Audinos in the wild? And I'm not speaking directly to EV training, either, I'm just talking about training in general.
