Bakugan trap, Darkus Tripod Epsilon. I gain an extra 390g. Nao, triple ability activate, Cool Snail, Daimond Snail, and special ability Rapid Baloon. Cool Snail prevents you from plying any future normal abilities, Daimond Snail negates all your active abilities (minus Shock Down), so Armored Mega Dome's effect is negated, so you lose 200g. Also, Daimond Snail also decreases your G-power by 200g as well. And finally, Rapid Ballon increases my G-power by 200g.
You-590g
Me-870g.
Unless you have a special or fusion ability to save yourself, I won that brawl.
