2. Once you have to STD someone, they should not be able to recieve aid, that is abuseable as hell. I could just have a couple guys net, sit marked offline waitinf to get low, then have them aid me to the point where I cannot be STDd (which does not take any work at all in Duels).
3. The Turn Bank is pretty useless, you might as well just raise max turns or make it fill slower with a higher cap. In a game like this, making it uber fast will serve nothing other than handing the game to whoever is most active, as mentioned before.
So if you want a nice little playerbase, you're going to need to fix some crap. Because I am not going to stick around to play a game where skill is not involved in any way like Duels. You could even apply those suggestions to BFR and whatever the other games are to get more players.
And before this argument is brought up, I am not complaining because I do not likt your code, sure, I don't like it, but it's pretty obvious that I am not alone. Your head's in the right place, just think things through a little more and it'll work out fine.
