Its funny how you downplay RSM Naruto's abilities yet fap Sasuke's coreless CT without having any proof that it could've worked when Sasuke who was trying to kill Naruto didn't even consider using it against Naruto.
Your claims of coreless CT would have worked could only mean one of the two things, first either Sasuke was dumb for not using the coreless CT or you're dumb for wanking an ability which Sasuke himself didn't think would work against Naruto.
There's a third option as well (Only for salty Sausage faps who can't admit the facts): Sausage was nerfed...
Take your pick.
