well all the cards necessary for a particular school is very subjective. that will be different for everyone. for example, you can have 6 of a level 1 spell and 4 of any others unless they are epic but most of the time you wont need near that many, so most people would be buying lots of cards you dont want. but i would like to see more types of spell tomes so you dont have to purchace a second boxed set or anything
