I got Heart Gold recently, and I was wondering, could you guys reccomend some guys that are really, really strong in each category to that I can get the Potential records for each. I can just go buy a billion pokeballs and do it, but this is faster.
Get aprijuice depending on the section to partake in or brew your own to work on pokemon you feel are best for each category. Each pokemon nature makes them good at some and bad at others. I think you just need to put your best foot forward.
