Here is a quick rundown of deployment types.
Refused flank, deploy your forces on one flank. Use scouts to trick your opponent into spreading their force. Then move your scouts with their free move back to the main force. Idea is to only face off against part of your opponents force.
Horns of the bull, strong anvil in the middle and fast hammer blow units on the flanks.
Castle, if you have a hill in your deployment area, put artillery on it and surrounded it with missile units and a few combat units to challenge any enemy units that survive.
Staggered, deploy with units forming a staggered line, with anvil units at the front. They take the impact, the units that are to the side and behind can then charge the enemies flanks.
I’m sure there is a lot more, but those are the ones that come to mind.
