I've found this listing on Mandarake for CSM "RIDERCARD OF DECADRIVER", and it confuses me. I'd assume it's some sort of alternate release of the Rider Card set that has all his extra cards and some binders, but that would surprise me since the Manda listing has it for 3000 Yen. It also doesn't seem to be Diend's Kaijinride extra card, and I can't find anything on it outside of Mandarake. Anyone have a clue?
