I have a Pawniard with PKRS and she is holding the Macho Brace. Will she gain 40 Att. EVs if she holds the EXP. Share and my Greninja battles the Horde.
YES because the EVs will be counted in this way:
[(no. of EVs given x 2 (pokerus) x 2 (macho brace)) x 5 (no. of Pokemon)]
[(2 x 2 x 2)5] = 40EVs
Hope I helped:)
