How To Be A Better Brawler
Get rid of you'r weaker bakugan. And, start getting the stronger ones! Thats how I won the game! The FINAL boss is the guy from the lab. He wasn't a human!
How To Switch G-power
To switch G-power, you keep training and keep unlocking cards until you get the card that switches you'r G-power with you'r opponent's G-power. Use this when your G-power is weaker then your opponent's.
Level up your bakugan a lot before battling. The higher level you are, the easier it will be to win.
