My victory date was late, so I feel a little embarrassed offering my thoughts.

It also helps, I think, to have an early means to generate one or more GGs before pushing out. As with the AW games, it seems that the pre-Catapult era is the easiest in which to defend with a bare minimum of investment. Monty is terrible at using the Jaguar Warrior, so he's as good a target as any to provoke.
Three settled GGs and Theo lets you build triple promoted units out of the gate. They also let you draft level two units, which allows them to be specialized immediately (Shock/Pinch) or heal after mopping up an attack. That's a huge deal if you're only facing medieval defenders and want to move quickly from city to city.
