Since the only goal is to come out the points leader, what's stopping Ginji just repeatedly dealing into Morita's hand on purpose? Or Kuramae's goon doing the same thing for Kuramae? There's been similar strategies in Akagi but in those there was more to it than finishing in 1st place so there was a little more depth to it. If you could secretly communicate with your ally you could just deal into each others hands to farm points.
