Their "fist fight" type of duel keeps at it. Things are really heating up. Bandit Keith is cheating though, by using cards that he needs tucked into his wristband, but Joey is answering all of his punches anyways. I'm surprised that Pegasus wasn't shown witnessing Keith's intentions, indicating that he saw Keith's decision to cheat. That would have been interesting to see, maybe he'll address it later.
Despite Bandit Keith getting the upper hand, Joey used his own move against him and brought back his Red Eyes Black Dragon back out at peak strength to take out Keith for the win. Great strategy.
