I really like the Air Shield idea for Marignon, it's a great addition for the Flagellants and very handy for dodging friendly Fire Arrows too.

Unfortunately it's not easy to build an efficient Pretender supporting both F9 and A5-6 plus good order/production/dominion for recruiting a fair number of Knights Of The Chalice and Flagellants per turn.

The most optimal Pretender build I got supporting this idea, from my humble point of view, is an Imprisoned Baphomet with F9A5S2, Dominion 6, Order & Production 3, Drain 2 and neutral scales for Heat/Luck/Growth.
Death scales are not recommended since our best mages/priests are old and prone to disease.

I found Baphomet surprisingly good for any build requiring F9 and dominion!! Even better than Phoenix who already has A1F1 and no additional paths required!
