[Scott Hebert]

I don't know much about MP strategies, and I know that the theme I'm about to suggest is perhaps a little sub-optimal, but has anyone thought of Fires of the Faith Marignon? IIRC, each of their provinces has a free Holy-1 Inquisitor preaching every turn, and if you start with a Dominion of 10 (Virtue or Glyph most likely), then it's just possible you might be able to win the dominion war.

If you choose to go the Virtue route, and you think you can keep your dominion up, you might also think about the Wrath global. Purgatory is another option.
