KA is restricted.
Assuming the battle starts with all hearts out, Fire and wind combined.
-Kakuzu counters any genjutsu, since the hearts has minds of its own and it responds whenever kakuzu is harmed,they can even move while kakazu is dead so one could just wake him up.
- Amaterasu is a problem, but kakuzu could just cut the burning hair off, Burning the hearts is useless, as they have no feelings and can just continue attacking, If kakazu tries to retrieve the heart out then he can buldge the burning hair out.
-Hearts is useless against susanoo via yata but kakuzu counters it by sending his arms underground, he can dodge totsuke because kakazu has shown to be fast aswell, prolly as fast as itachi
-Itachi has no large scale attacks like FRS to wipe kakuzu together with the hearts, If he spans yagatama he will die of exhaustion and kakuzu can counter via fire+wind masks.
In the end its up to one who can outlast eachother which goes to kakuzu,
I'm not saying itachi is weak though he's really powerful but i think kakuzu is a bad match up because he can outlast him and can give him a great fight too.
The end
