The design of the troops looks really nice in my view. The powers also seem very strong.
But what the heck are those merchant caravans? Is it an early April Fools’ joke or are they really going to keep the ‘mechanical bull’? It was a good opportunity to introduce an animal historically used for this, like they did with camels, for example. Why waste that opportunity by adding something with such a poor concept? Ugly in motion, ugly to watch moving.
I have to admit that they look a little bit goofy and out of place. And a civ with a special myth unit caravan option doesn’t need something that ‘‘spacy’’ as the regular caravan haha 
Something like the Yak caravans from tale of the dragon would have been better maybe.
Because the mechanical bulls are very famous in China. Almost everyone in China konws them, they are the invention of Zhuge Liang in The Romance of The Three Kingdoms. I personally think this is a good idea.
