The whole point of using a Card Disc would be to save time while levelling so you don't have to go clear your inventory as often.
Right now as you have to manually store the card inside the disc, it still means you have to stop your levelling and do some inventory management, which I don't want to do.
As it is, the Card Disc is simply a expensive and worst version of a lvl 20 storage character that would follow you around on a board.
