Thanks that helps a lot ^_^
I just have one more question though... I recently decided to re-ev train my gardevoir so I got a ton of the ev-lowering berries. I used them on gardevoir to reduce defense, HP, and attack until it told me that it would have no effect. So I assumed that meant those evs were empty.
Then, I went to battle frontier and bought a bunch of vitamins for special attack and speed, but I could only use two or three of each. It seemed to take quite a few berries before it told me it would have no effect, yet I could only use a couple more vitamins which give as many evs as the berries take away...so is there some sort of vitamin limit or...?
