Epoch is going whole hog on team sets this year, putting up a bit of competition to BBM. The first set they released, on April 7th, was Carp Rookies and Stars.
Each 5-card pack retails for 400 yen, with 20 packs per box and 12 boxes per case.
Additionally, the six Rookies players have Authentic Signatures cards with various numbering. Each rookie has three versions with different photos on the front. Numbering differs slightly for some players, but generally the print runs are about 100 copies, 70 copies, and 30 copies.
