But is there any way to tell at the store which Starter has the 700G+ Bakugan in it? Computer turns off in 6 minutes, 6 more minutes of chat time xP
If you know the Bakugan's closed ball form, then you can determine if it might have 700+gs. It would need to be a Bakugan in the "Strongest Bakugan" section, or another one with a 700+ form, like many B3s.
Yes, 700g+ B3s are common. In fact, exactly half of my B3s are over 700 (the other three are under 700, and no 700 exactly), Neon Thunder WIlda 710g, Crystal VErias 710g, and core Darkus Moskeeto 740g (which also comes in 700g, like Lux's).
