Well the third gen standard was something like CM/Recover/Toxic/Psychic I believe, maybe reflect over toxic, so I assume it's mostly the same. Maybe aeroblast over psychic because it's special now. Or Ice beam might be more useful in Ubers. Roost could go over recover to be neutral to ice beams etc. I suppose
EVs I would assume to be alot of HP, and the rest split between def/sp def/sp atk, I'm not really 100% though, because I've never really played Ubers.
