Well, actually it doesn't come down to luck. Each pack has a pre-set bakugan with a predetermined Gpower and cards. IE, All Boosters with a Pyrus Moskeeto will always come with the same Gs and cards, whereas in a starter it'll be different. Sometimes, not often, they will be different, so always bring a pin to scratch off the sticker.
...and you don't get into any trouble for doing that...?
No, I only poke them in one or two... I usually end up buying it because I know what I'm getting before I stick the needle in, I just do it to make sure.@Justin because I'm to lazy to quote: Get a needle, poke a hole in the plastic, scratch off the sticker with the needle, ??, profit.
