Sounds interesting! I think the "packs" idea is interesting, but I would prefer that they made it so that both players drew from the same pool of cards. That way, the person with the most skill would win, as opposed to the luckiest draw.
Can't really knock it until I see it, but I'm really interesting in finding out about the reward cards! Also, the war-bond thing is going to be interesting...kind of like online poker, lol. I wonder if they'll send a deposit directly to your bank account?
