Mictlan Pretenders ideas request

[PDF]

Hi,
After suffering to Mictlan in a number of games, I begin to realize there is maybe something to do with them (mostly mass demon summoning )
But I've no brillant idea about a good pretender... Basically, is a Blessing strategy really useful (the sacred troops are just ok, nothing great IMHO), or rather should one go for a big Blood mage (to get the big blood stuff easily) , a magic poor SC to help the (crappy) troops, or stg else ?
I suppose Mictlan requires good scales (except Prod), medium dominion at least and a cheap fort, so is en expensive pretender worthwhile ?
