So, I just learned about IVs the other day (as if I didn't have enough to worry about with Natures, EVs, etc), and I'm wondering if there's a way to change/control your Pokemon's IVs. For example, I'm hatching lots of Eevees lately in the hopes of getting one that will make a good Jolteon, hopefully with a powerful Hidden Power Grass. However, it's proving trickier than I thought, since the only thing it seems I can do is hope for the right combo. Any advice from you more experienced breeders?
