Commander needs to be a priest to be able not to take additional commanders.
In my game with mictlan I empowered a Tlahuelpuchi in death and summoned Civateteos. Civateteo is an excellent commander for the demon groups and those groups with decent bless (I had W9D9 PoD) can take out almost anything. Ozelotles are really great but bats, I think, are not worth using, 'cause your national troops are better.
And you really need to give Civateteo the Winged shoes. That's where your national heroes help. Mictlipoctli will help to summon civateteos without empowering and Tepeyocatl should be empowered in air, search sites and later forge winged shoes for you. Air is really important part of this strategy. Another way to get it is through Obscuro merc.
