Isaiah is a must. Seraph w/ live coal to go with him. Hosea is great, if for no other reason than that he makes Gomer negateable. Habakkuk, Micah and Nathan are also advisable. Cherubim and Seraph (just make sure you have the right one if you're also using w/ live coal) are great, maybe splash in Michael, Captain or TSA for more silver. If you're using a bab defense, Ezekiel and the other associated cards would be great.
