The EV trainer in the secret base takes too much time, are there better ways to train EVs?
- Buy the “power items” from I think Helios Dept. Store (bracer, lens, etc.) they add +4 EVs to the matching stat.
- fill up your team with as many pokemon that need EVing as possible and give 5 of them EXP shares
- find a friend safari that has +2 to a stat Pokemon (I.E. Pikachu has +2 speed EVs etc.) That nets 6 EVs per battle, for up to 6 pokemon. Here’s the old list
Friend Safari EV Training Spots
If you can get PokeRus you can get 12 EVs/Battle
