Forum:Crystal beast deck question

My brother plays a crystal beast deck, and he was thinking of putting a The Calculator in his deck. He says that since his monsters in the spell and trap zone are still considered to be monsters, although they are treated as spell cards, he should be able to add up the star level of his spell monsters and apply them to his calculator. I've tried to argue that once his monsters go to the spell zone they are basically treated like spells with no effects. So I guess the big question here is, do monsters have any attributes at all while in the spell zone?
