Take Mictlan, do a F9W9 moloch, turmoil 3 sloth 3 heat 3 drain 3 growth 3 luck 3, dominion 7, watchtower.
Just build hordes of jaguar warriors and eagle warriors and overrun your enemies with sacred hordes of doom
.
As long as the map is not bigger than around 80 provinces and unless you don't fight caelum/man/vanheim or pythium your opponents should have nothing to beat you in the first 20-30 turns.
I mentioned those 4 nations because they are all 4 airnations and thus can research seeking arrow quickly which will hurt your priests and thus eventually stop your advance or at least delay it significantly.
The longer the game continues the more vulnerable you get.
But playing with a dualbless is great fun and very exciting in the earlygame and midgame. Can you overwhelm your opponents quickly enough? Or do they find something to delay you long enough to develop countermeasures?
