Shibisu is a decent tactician. To his credit, the guy can work out a plan and execute it well, but at the end of the day that isn’t quite enough to take on someone who is essentially pure power. Bam would be able to easily overpower him thanks to the wonders of Shinsu and the fact that Bam is just a gifted fighter. He should be able to win the day in a matter of moments. Bam wins.
