In deathmatch AOC I usualy spam Elite Bowmen till they are 110/200 of the overall population they don't do much damage inidividualy but 110 of them will cause a problem. however this requires good economy management they are terrible effective even against a mass of War Elephants however siege onagers are abe to take them out very quickly they have very low defense.
We usualy play random civs and random teams for an extra challenge , it requires alot of versatility at first but then you understand the strengths of every civ and it becomes second nature.
