I've recently played through Emerald to get myself a better Groudon: I'm going for a physical one, so obviously Adamant would be a nice nature, but on one of my restarts, I caught a Jolly, with max IVs in both Special Defense and Speed, and a 21 in Attack. The lowest IV is a 3 in it's Special Attack (heh). I'm thinking this would be a good choice to keep, but I'm not fully sure, or sure if I should adjust my planned 252 atk, 252 spd, 6 HP spread. Any advice?
