What I Would Do Differently:

Having more units helps to keep squads fighting. Having only one mammoth is a bad idea. Having a mammoth and 24 units would't be very good either. Having few mammoths and 4-6 units fares much better. Especially if those few units have high morale. That means either Wingless or Temple Guards for Caelum until you find something more interesting.

Vampire Queens need their boosters in most cases, so both fliers and cavalry can be a hard opponent. She is immortal though, so she can just wear cavalry down as she will be able to cast some of the more important boosters and finish some of them.
