Okay, before you write this off as the stupidest possible question on the planet, hear me out. In a playthrough that I'm doing, I have a Gardevoir. It has a brave nature, since I was tired of looking for Ralts that seemed to refuse to show up by the time I found one with Synchronize. Now, before the league, I decided just to go all out and hardcore EV train my Gardevoir. I went to Oreburgh Gate and murdered every Zubat and Psyduck in sight with a held Macho Brace. I fought about an equal amount of Zubats and Psyducks, and I gained +3 in speed. However, I also gain +17 in special attack. I was a little confused, so I just fought another level's worth of exclusively Zubats. I got +2 in speed from that level up. And now here I am, looking through Bulbapedia articles and finding nothing about EVs and natures and base stats and all that. Does anyone here have any idea what's going on? (I'm playing Platinum, for anyone wondering)
