Ok, why are people comparing Tsukyomi and other genjutsus to KA? KA is superior to all other genjutsus. I mean, it's so OP that Kishi decided to nerf it by giving it a 10 year cooldown. Hell it was even able to get Itachi out of the impure world resurrection technique. Truth is, we don't know if KA will work on Jinchurikis or not. NO ONE has any proof whether KA works on jinchurikis or not.
I have to admit, Shisui is pretty OP in a 1v1 versus battle. In Naruto reality though, because KA has a 10 year cooldown, Shisui can hardly rely on it.
