Best sacred units?

If a Ghost King is running arounf as Pretender, quite possibly. And said undead can hide, I think: under heavy robes, it should be hard to figure out your good ole pastor is actually a Revenant. Of course, mindless undeads need not apply.

Without naming any specific religions, many religious leaders seem pretty mindless to me: "Do what I say, go to heaven... Do what I say, go to heaven..."

I'm fond of Greater Othernesses, as they nicely compensate for R'lyeh's weakness in melee crunching, and being void summons don't cost upkeep.

(Yeah, they have Meteorite Guard, and Lobos; but the former are hideously expensive, and the latter unarmored, if memory serves.)
