I like the Totem idea, but:
* Is it not unmoving? Why does it have better fighting skills than a Celestial Master?
* The Ceremonial Master that the Totem replaces is not a BK-only unit. So why not just add it, since it will appear in other themes anyway?

I very much like:
* Reduced Barbarian Horseman cost.
* Added pillage bonus.
* Increased accuracy.
* Wasteland Survival.

I'm not so sure about:
* Added Fear ability.
* Very high morale.
* Added attack skill.

I might suggest:
* Even lower Barbarian Horseman cost, but also losing some of the abilities back where they were (Fear, Morale, Attack skill). Barbarians aren't accustomed to a high gold salary, and Khans rule them by strength, leadership, and fear, rather than by paying them a lot. So it seems appropriate to have them have exceptionally low gold cost. Fear and morale will then come as a natural side effect of having a whole bunch of them due to their low cost and ability to survive without supplies, rather than due to a supernatural Fear ability and high base morale.
* Add Plains Survival as well, and/or maybe Supply Generation or Need Not Eat, because nomads are hunter/gatherers.
