Okay, so before I mess up my EV training:
I go into a battle, leading with my level 10 Sneasel with Pokerus and Power Bracer. I'm fighting the guy with three lvl 30 Gyarados'. So, when I switch Sneasel out for Pokemon x and beat Gyarados 1, I'll get 4 attack EV's from the Gyarados and 8 attack EV's from the Power Bracer with Pokerus multiplier. And after I switch Sneasel out for the two other Gyarados', I will receive 36 attack EVs in total, from all 3 Gyarados.
Are my calculations correct? I can switch out my Sneasel in such a manner and get my 36 EV's?
