thats what ive been doing... but i know my pokemon has a couple IVs that arnt perfect, but are very close. i wish there was a was to see without having to EV train it. i guess i could casually train it real quick, use a reset bag on its EVs, then check its IVs?
Does the Battle Mansion or the Battle Tests auto-level to 50? I haven't tried either with any pokemon under 50, so I can't really say.
