another great way to get more money and have your pokemon gain exp points is to verse lots of pairs (two people in the one battle, they are found standing exactly nect to eachother) as both your pokemon gain good amounts of exp points,if u see to people next to eachother than i recommend that if u have pokemon that are weaker than others or certain ones that you want to move up levels sooner than i would put one of da pokemon that u wanna battle with in the lead, and the other one at the top of the list cause those are the ones that are alwayes chosen, also once u have beaten the elite four on 1 island there is a pair, two karate men and a lady running around, all of their pokemon have grown to like level 50 so u get more money and ur pokemon get more exp points
