It's nice to see how Oda accounts both for Zoro's strengths as well as his weaknesses this chapter.
He does not have the mobility/speed to get in position to stop Kaido's attack aimed at Luffy as well as launch his own attack at him from that height, so he needs to rely on Law to teleport him there, but he does have the best lethality, and his attack with Enma is hyped up the most in that regard as a dangerous one.
