Why the reversal of the main Luxury colors...?
More to the point, I have a hard time seeing a collecting card game work with only 13 or 14 characters. (They may not include Kotori.) 16 or 17 if they include the base DS idols. (Equally as likely as Kotori; however, their likeliness is for all of them, and seperate from Kotori) Add 2-3 more if they include Yumeko, Cineria, and even less likely Mai. (They won't, though.) It can be done, I guess; but not as a card GAME surely. Maybe if it's just a "collect and trade cards" thing, it might work. I feel bad shortlisting the game's potential because of Cinderella Girls, but I don't see how it can bring anything new to the table. Considering the heart, star, and (what is that, a diamond? A sparkle?), along with the pink, yellow, and blue backgrounds, there seems to be a type system of some sort, one eerily alike to CGirls' Cute, Passion, and Cool, respectively. But the idol choices seem to betray that. (Mostly Yayoi; I might see Ritsuko in Passion, but Yayoi has no place in Cool. None.)
