I'm also very curious about the differences between characters. It seemed like all the card art I saw had the character that I was using on it, so my guess is that each character has a different set of cards that belongs to them. Wish there was some confirmation of that available to the player before unlocking the other characters.
I like the storybook art style. Not that sold on the gameplay yet, I would like to see the difference between characters.
