Do you get the bonus EVs for a macho brace, if you switch the Pokemon with a macho brace out and then win the battle with another Pokemon?
The Pokemon holding the macho brace will get its EVs doubled.No effects will occur for the second Pokemon.
Yes, but the regular Evs are halved.
Ex: If you got 2 EVs normally, then with Macho Brace, you'd get 4. The MB Pokemon would get 5 if you switched, and the second Pokemon would get 1.
