Im surprised that this wasn't suggested but i searched and didnt see it
I know mission cards have been suggest but how about command cards. for those of you who dont know what they are what happens is that along you get the same number of energy points as you would get troops. then in between the deployment and attack stage you could perchase command cards. they say things such as get a bonus three armies on a selected territory or all troops but one disapper on a selected territory. At any point while you are attacking you can use them. different cards cost different amount of energy to use.
what do you think
