I didn't look at all the Ability Cards thoroughly but I know that you won't be able to use Shiny Devil because your opponents printed G-Power must be 200 points or higher for you to actually use it and you've got just about all the strongest Bakugans in that group. And I'm pretty sure everyone else knows that your team is food for Duck & Win cards.
First of all i checked ebay, no one was selling one and two that's why i'm getting a low g so i'm not open to Low Bridge moves and to use Shiny Devil as a last resort
Well just 1 low G Bakugan won't help since if you're playing the Big Game style, I would presume you use 6 Gate cards, 2 of each color. And there are plenty of different “Lowest G-Power wins” cards. So you would need at the very least 2 lower G Bakugan.
