Good concept, but I want to be able to experiment with different unit loadouts, try them out before I throw them at the next mission and right now I can't really do that. I think the addition of a random skirmish mission, or just separating player-created army battles from the main story missions, would make this a great game.
My suggestions: 1) Ability to sort cards by ability (grouped by faction restrictions), timer, and set. 2) Nobody likes the energy system; I'd at least be okay with it if I only lost energy when I *won.* 3) Mission opponents sometimes get more than 10 cards to use. WTF?!
I'm filing a complaint with the BBB about this superplane dealer. When someone tells me a new flying killing machine comes with four weapon slots, I expect all four of them to be there when I fly it off the lot. >:[
