Hey Valt, from what I have seen the last few weeks not one deck is really to much better then the rest for the bot. I use very basic rouge/mage decks when I run it (nothing that the class can't earn from level except ragnoros, the fire lord) and the bot will usually run a 60-70 win rate. Though on ownedcore I do remember reading some body saying that their zoo lock deck had a 80% win rate using this bot, not sure how true it is but I guess worth a try. Good luck bottng!

P.S. Bot bit buggy after the Naxx patch so don't let it discourage you from this great bot i'm sure the bugs will taste a nice leather boot once the creators get a chance.
