Dragon V2
Dragon V2 is the Kaido-line awakening: transformation pressure and space control. Still Mythical-tier on this wiki’s PvP list.

Own Dragon (Kaido can drop it), then awaken. Boss farming on Wano is the obvious Dragon path if you refuse to spin.
Why
You want big windows, not 12-hit singles. Use height and transform timing; do not waste the form on a 1v1 you already won.
