man fire is the natural enemy to mochi, as water is the natural enemy for Crocodile.
Whatever you use hacky, the fire effect still can melt the mochi. It is the same argument you guys are using for captain mid with the magnetism shit.... of course hacky can help but there is always a nerf to the user especially if use in close range metal weapons.
Same shit is applied to the mochi guy, his stat goes down when fighting a guy that can control use fire like King (his fire does last too) Zoro was burning when reaching to the blades and Zoro has better coa than mister katakuri.
Second acoo is pretty much useless as we saw the rooftop fight, nothing I repeat nothing that Luffy used before chp 1010 was bothering Kaido (luffy is saying all attack were to shallow, and Luffy running out of hacky getting carried for 1 chapter then getting KO in chapter 1009 proof that advcoo didnt help a shit in that fight). As such adcoo is overhype, but adv coc that was praised directly by the so call top current strongest character in One Piece (community is putting Kaido as first) is the key for Kaido defeat.
Nothing would have work on King that Katakuri has. He need to coated his attack with coc or there is no win for mister Mochi.
Kaido potrayed is superior to old Rayleigh, and basically Kaido confirmed that adv coc is superior having both > adcoa and adcoo.
