Ive come back on Bakuganbuzz and found all this stuff about B3 Bakugan. So far I have managed to understand it.It seems that there will be a different type of pack for different type's of BakuganFor exp.BakuCore=Main BakuganBakuFlip=Flip BakuganBakuSteel=Steel BakuganBakuCrystal=Clear BakuganDo you understand it. As each new series comes out they will be placed in all the different packs. With Each pack containing a different type of Bakugan. With BakuCore been the main.
bakucore is shadow treatment
