Hm...the commonfolk should have cards too, and some Classic types. You could have all colors and flavors of Zero 33 for common cards...or maybe have several Zeros of varying rarity... "Whoa! A first edition greenhair Zero 33 with star shield!" Azrael and Bruges would also be musts, and Tyhm would have to be a pretty good card with perhaps some sort of power to alter reality.
