Hee. I think "protection from Demons and Dragons" is somewhat unnecessary when you have prot black and red. But otherwise, delightful idea. The set would need rules support for attacking creatures as though they were players, so you might want another couple of rares with that mechanic (it's complex enough that it shouldn't appear at lower than rare). But this is a very flavourful and fun approach to it.

Changed it to be very hateful against demons and dragons so i didn't have to insert provoke in the mechanics
