The Eight-Tails vs. Sasuke!!

Summary
Sasuke attacks Killer B with his sword, aware that he cannot kill B. That some stipulation does not apply for B, who uses Suigetsu's Kubikiribōchō to spar with him. B is impressed by Sasuke's skill with a blade, so does him the courtesy of using his seven personal blades instead of Suigetsu's. Sasuke has difficulty keeping up with B's many strikes even with his Sharingan, but believes he has the advantage of channeling lightning into his sword. B also has that advantage, which he uses to stab Sasuke with multiple swords.
