I caught Raikou in ORAS on my second try (he Struggled to death on the first) and I took him to the IV judge. He has perfect Speed, Sp. Attack and Defence. However, he has poor Sp. Defence. Should I keep him as he is, since I have most of the IVs I want, or keep trying to get that Sp. Defence IV? (He's going to be using Assault Vest.)
