It might be just me but since you need to play A-bomb on a evil greek character, you might want to put some black greeks in there.
It depends on how much you want to abuse/ be dependent on A-bomb.
I would put in 4 or 5 greeks - Antiochus, The Winged Leopard, Di greek demon, any other good ones?, and Greek Scholars and Philsophers. The new demon recurs A-bomb, but I would also try to fit in the Di Scribe? that can recur it as well and maybe even King Amon and Manasseh, though I might run out of room for it. I would definitely put in Pride of Simon for another recursion. With so many ways to easily get rid of placed evil enhancements it would be important for me to easily get it back.
You obviously include all heros that make them draw (hopefully you were at nationals and made yourself a gold hero that makes them draw).
For offence, I would put in Hidden Treasures, a couple green prophets, Unity in Christ to band in the red guy that negates sites and Martha etc, for multiple A-Bomb use. I would also put in Search to get A-bomb earlier, Sword of the Lord to create another way to play A-bomb, and maybe Visions of Iddo the Seer to save your heros. also add Mentor, Ethiopian Treasurer, and battle cry to again band in all your heros. another way for multiple drawing is to block with King Reheboam and pick Martha and Generous Widow. Since my version is more dependent on the hero abilities for drawing, I would put in a couple ways to heal or return them from capture and add Chariots of Fire. If you're using Joidia and Feast of Trumpets (and you probably should) then you will have Z-Temple in there but I wouldn't add much to go with it. I don't think you need Garden Tomb but you could add that and one Garden Tomb hero for walk ins after A-bomb has cleared the territory.
