I've always liked the idea of spell cards with one exception - I wish they had individual art, unique to each spell, on the backs of each card..
It doesn't have to be anything elaborate, but a simple fireball on the back of the fireball card sure would bring some personality to them..
The front of the boxes look nice - I'm certainly not asking for something that involved on each card, but a tiny bit of art goes a long way..
I realize some spells that aren't of the "blasting" variety could be tough to illustrate, but I still think anything is better than the same generic symbols they put on each card..
