Yeah, on Pokemon black, using the Macho Brace.
For instance Gyarados with 252 EV on attack and 252 on init. The rest to vita
Gave him 10 vitamines

152 left for atk and init.
/2 because of macho brace

76 pokemon ( or 38 )
Depends on how much the according pokemon gives.
So I need to kill that much pokemon and I've finished my EV training.
Ofc. I can traing a staller Pokemon like Umbreon via exp share, because it also gets its ev then.
But after that, still without attack move, I still need to use the exp share getting lvls.
Another option is the pension or the candy and also the Pokewalker.
But my Pokemon also learns attacks by lvl so it is quite irritating.
In my opinion..
but i thought that when you battled online, pokemon were automatically lvld to either 50 or 100 with their respective evs
