No, that's the problem.
So it's a random number, but if say Stronger got the package with a 5000 Snapzoid (I know it's not real, I made something up), he'd post the number, and all Snapzoid packs with that number would have a Snapzoid with 5000Gs?
Okay, I think your on the right track. So if Stronger got a BakuBoost containing a Snapzoid with 5000G's in whatever attribute, the number on the back would be the same to the others containing the Snapzoid. So let's say the number was 9023422347. Go across the country and find a Snapzoid Booster with the same number. It should have the same Bakugan with the same amount of G's. The cards are another thing.
