Strategy powers

Simple each strategy has a power u can use in the game it lasts 1 month (4 weeks) and can only be used once every 5 months (20 weeks) EX: PD is a strategy a players uses its powers give infantry a bonus 1 def could give the player a edge in battle when he really needs to defend a capital win the war and so on. this is just a idea that 99% sure wont be put into the game but its a idea

Like risk? in where i place cards for units? maybe idk.

What?

Strategy you choose to play with already have quite big impact on your units and gameplay, it could make a game harder to balance and also there would be situations when you lose a battle only because some guy used a card (battles are already allowing quite a lot of randomness).
