I am doing really well in one game as MA Mictlan. Some comments:
- single S9 bless makes initial expansion a bit too slow and scales are just too good to make use of them
- S9 pretender rulz end game
- don't rely on randoms on Nahualli, I never got blood random with over 100 of them recruited
- best way to get into blood would be to summon Tlalocs [yeah, a bit late]
- you could think about flying/teleporting communion casting Master Enslave later
- you really need to site search for earth, alchemists are great if you can find them as they can summon golems, which can teleport together with your mages
- hordes of chaff are wonderful
- I would try to cast Maelstrom so you can get water gem income for clams
