Kata’s CoA was stronger than Luffys prior to his Udon training and I believe he dan inflict some damage with Mogura piercing attacks to be perfectly honest.
If Kiku can stab Kaido then I dont know why Kata cant stab King when his dura hax is off.
The last thing is a reach, Kata is tagging King 100%.
It was still level 1 COA while Zoro with level 2 COA and Enma boost couldn't get past King's defense. Mogura's too slow to tag even base Luffy, forget about King—who kept up with Marco's hybrid in base. Mogura never touches King's speed form.
Well, Zoro did try to stab King and this happened:
Shape-shifting can't help him against this attack.
Katakuri and Luffy aren't the only people who can move fast in this manga. The others can do it too. Lunarian hax gave King a defense that can rival that of Kaido, so if it is anything to go by, then his speed should be in the top-class as well. As a matter of fact, he was fighting Marco's hybrid in base and still somehow managed to tag him and defeat him. His speed mode should be something else.
