If zynga had a badugi game, the play would definitely be worse than Stars play money...lol
But in terms of real-money online play, yeah merge is your best bet. I think you can sign up for rakeback again now (don't quote me on that) as well. Other than that, you're better off going to Vegas to find live games. And badugi live is usually only run as part of a mix game, often for higher stakes.
If you would happen to live near St. Louis, we could play HU, haha.
