Another suggestion: you should make it so that we can see how many battles we've defended over the past 24 hours and how many points were earned off of our decks. This would allow us to fine-tune our defense, as we could make adjustments one day and see the results the next. As it stands, we have no idea how well our defense does against others.
I think adding a "break" or pause button would be helpful when you're doing automated combat. I tend to forget that I'm on auto...so that when I go into a mission or a war, all of a sudden I'm using Electromagnetic Pulse as my first card. I read someone else suggesting a "prompt" option, but I think a "pause" or "break" would be better--prompts get annoying.
Great game, though :)
