About this product

This starter deck introduces The Idolmaster Cinderella Girls to UNION ARENA, with cards featuring the series’ idols. It also includes a promotional R pack containing four new card designs with effects not found in the main deck. Those cards represent two attributes different from the deck’s, and the pack contains one of each design; parallel artwork may also appear.

A paper playmat featuring The Idolmaster Cinderella Girls artwork is included. Some cards have alternate illustrations of cards from the matching UA55BT booster set.
