I think one additional point that needs to be brought up is the Skeptic Prophet. This is probably your best choice for a Prophet (unless you have a high-Earth pretender and get Orokestes), and this guy is very good at destroying enemy dominion. He has the following points:

1) Inherent Dominion reduction (Skeptic effect)
2) Automatic Preaching (Prophet effect)
3) Able to Preach (Prophet makes him level-3 Holy Priest)

I'll also note that it's not hard for Golden Era Arco to make Stone Idols, which would improve this strategy even more.
