My preyas bakugan doesnt have the symbols to change his attribute what should I do

Well there are only a few preyas bakugans that have the symbols to change the attributes (they are very rare you can hardly find it even at ebay.com!!!) so sorry man you didnt have luck!, i have one with the symbols i found it at walmart but it was on a plastic bag (so i didnt saw that it was a preyas) but when i opened it it was a changing preyas (with symbols)!!!!!
Hope it helped
