I have Arkham Origins Batman (Yet to Promote),Doomsday prime (Promomoted to Elite-1) and Darkseid Apokolips ( Promomoted to Elite-1). Apart from these, I have three more gold characters (Wonder women, Black adam regime and Bane regime). Should I buy this Challenge pack or just keep promoting these characters?
