Thanks =) i'm very busy at work that's the reason for not learn quickly IV's, besides i need an AR for checking IV's quickly, or find some software that do that on an R4 flash cart?
Yeah, AR saves you a lot of time. But if you can RNG for shinys you can RNG for IVs. On HGSS anyways, they're basically the same thing but you have to input IVs. Which is why its best to have a parent with near flawless IVs.
