Did you forgot about that one ccg game? I think it was Angelic Saga or something. From what I remember, it played kinda like Yu-Gi-Oh, with 5 unit slots and 5 Spell/Trap slot. It was nice, though a bit grindy.

Not too sure what happened to it, but looks like it's not on the games list anymore, so it may have been dropped due to profitability being low.
