It really all depends on your bakugan you want to use and overall strategy. Theres 2 basic “themes”, high g-power beatdown or sneaky low g-power control. But you can basically just pick 3 bakugan you like and then pick a card in each color that will benefit them the most.
Yay, my first bronze =OIt's a pyruse helios, it has 600gs. I found him at Wal-Mart, next to a Sub-terra Leefram and Pyro Dragonoid. The cards he came with are Flames of Light and Mega Nemus. Sorry I couldn't get pictures, my camera sucks ._.;
