Note: Almost all of this information is on the Celts.
To begin, Mr. Savanna (Celts) went a little overboard with Seige Workshops. He did good creating villagers to work on resources. That is one thing some players forget to do and they run out of resources. Mr. Savanna's military skill were below expectations in the beginning, but they soon began to kick butt. One idea that would have done well was to have a cheap unit like a pikeman, draw his enemies in. Close behind his pikeman should be seige onagers and they should take one shot and it should kill most of their units. If you lose a pikeman theres no big deal about it. However, with archers and ranged units, this would be a little bit difficult to pull off. Mr. Savanna did a very good job in the middle and the end. The following are some ratings on a 1-10 scale for a deathmatch:
Militaty Skills: 8
Use of Civ. Bonuses: 10 (mostly for his use of seige weapons)
