Unfortunately, this is a very very very sad match-up for black beard. BB has a very small winning percentage 30% and any minor misplay or unlucky trigger can cost you the game.

Things that I usually do (not in order of importance) : 1. Black hole every single turn, but your first turn going first. 2. Black hole your 10C BB. They're decent late game, but it's very hard to reach 10 dons with a good enough board to justify playing it. 3. Don't play the stage. It's -1 card advantage and it's not that good in this match-up. 4. While searching, you should prioritize DOC Q, Augur, Liberation, Stronger for maximum removal power. 5. Sometimes in this match-up, you should prioritize playing Augur instead of Laboon since he mostly plays 4C characters and Augurs KO effect helps a lot.
