My strategy on those cards for now is to use them on the rarer extra classes, eg Alter Ego, Avenger, Foreigner and Moon Cancer. (Not so much Alter Ego now that 2nd Mecha Eli-chan got me a 3rd but you get my point) I figure this way because when their class is necessary for Challenge quests I really only have the one servant to fill the role whereas when one of the standard 7 classes is needed I can load up with a couple backups as I have a selection of them.
