Nah, MA Mictlan is average nation. Sure, they have sacreds, but taking good bless kills so many options for them. D9W9 imprisoned Master Lich was somewhat a way to fix that in LR, but well, I still had problems
What I'd like to see for MA Mictlan is the way to play non-bless. Some troops that would let you expand. There are really good options for mid-game this way - flying communions, cheap researchers... but you just cannot execute it when your only option to expand is with sacreds.
