It's been a while since I've actually played Diamond or Pearl. My friend Armando regularly asks me to do doubles battles against him (boosted to 100) so that he can record stats to calculate IVs for breeding. Other than that, I burned out a while back EV training. I may pick it up again some time, at which point I would do my damnedest to get a hold of the G/S/C starters. They're the only ones I don't have yet.
