If you want to replace Monstra, perhaps you could use the dracolich sprite and make a tartarian dragon? Although it would likely have some of the same problems as the monstra (lack of slots mostly), they could be solved by allowing the dragon to shapechange into a bog mummy or something.

Also, about EA Agartha. Why do they use bronze? They are an underground nation with a good connection to the element earth. The fact that they haven't discovered iron is stupid. It would be a trivial job to recolor their armor grey and it would improve the horrible infantry (and perhaps make it useful when combined with some stat changes).
