*Shrugs* I'm not too sure, I know a bunch of people wanna stop CS at PCNY though. The only problem is, most of the time when you find a deck that's good against CS, it crumbles against all others, so yeah...
Well... since you're running Teen Titans... Hmm... All I can say is hope for the best of luck with your draws, if you get the stuff you need when you need it you'll win, although just an average draw from a CS deck can prove fatal sometimes.
Beyond Betrayal, nothing pops in my mind that's decent, and even Betrayal is only good on turn 7, and many games I've played with CS against TT I've won on turn 6. Now, regardless of what others may say, I've always had a horrible match up against Brave and the Bold, I don't know why, but I always have.
If you're looking for a way to stop CS and maybe have a shot at making day 2 then BNB is the way to go, either that or TNB (New Brotherhood), those are the worst match-ups I've ever had (and I run CS btw), my best have always been against straight TT, mirror matches, and recently with the addition of Total Anarchy any Cosmic Radiation deck build. Ever think about going old school and try a Wild Vomit deck? I lost to one of those once... but then again, I should have beaten it since I lost due to time being called and at the time I was still new to VS and I didn't know I had an extra turn to play.
If you want to try and think stuff up and then playtest it then let me know. I'll be arriving into New York around 10:15 AM or so (well at the motel in NJ around 10:45 AM at the latest) and we can get together and maybe just playtest a few things.
Just LMK.
