(Mock Battles from the Vs. Recorder)
I understand you cannot gain any experience, but I was wondering if they gained EVs anyway, such as a level 100 Pokemon would. Thanks.
No, you won't. Anything related to online or simulated battling (anything with level restrictions) will not yield EV points. However, Secret Base battles will give EVs.
TL;DR Mock battles do not yield EVs.
>However, in battles that do not give any experience (such as in the Battle Tower or if the Pokémon is level 100), Pokémon will not gain any effort points.
No, you will not gain EVs from any battle that does not give your Pokemon experience.
