I don't think any of the Mictlan summons have Holy 3; at least in MA, they Blood-7 one (requires B4 to cast, costs 101 slaves, autogenerates sacred flying demons) is only Holy 2 (pretty important since it's the difference between Blessing and Divine Blessing).

At least in SP, I've found that a pretender with Blood can be used to turn MA Mictlan into a decent Blood nation, even though none of the national mages have Blood (OK, one of them has something like 2.5% chance of having B1). And, you get the benefit of normal dominion spread, plenty of Sacred summons and national units; yummy!
