I am trying to ev train my Volcarona, and seminars seem to be the best way to do it. I know that the power lense will increase the amount of evs gained, but will the macho brace do the same?
The Macho Brace is a held item introduced in Generation III. It doubles all effort values gained by the holder during a battle.
It won't double EVs during seminars. Additionally, if you have the DLC, you should just buy Vitamins in bulk from the Dojo vending machines. It's far more convenient, provided you've gotten that far and you have the money/Watts.
