Danzo stopped it.
Madara's Tsukiyomi>>>>>>>>KA
He does have tsukiyomi if he didnt how could he do the Moon eye plan?I don't even believe Madara has Tsukiyomi. The only genjutsu he has shown was when he showed 13-yr old Obito his plans. Then he used genjutsu on the raikage, but the manga referred to that as "sharingan genjutsu" and he was using his 3-tomoe. Madara is relying on the Juubi to somehow cast the genjutsu and the moon will reflect the genjutsu across the entire world. But his genjutsu prowess doesn't seem to surpass Itachi's or Shisui's. Only perhaps Obito's.
Itachi's Tsukiyomi=Shisui's KA. I know that KA is stated to be the most potent, but the only advantages I can see with it above Tsukiyomi is that the victim does not know that they are being manipulated. Obito and Itachi can still manipulate people w/ their genjutsu, Obito manipulated Yagura the Mizukage for years. And Itachi cast a weak genjutsu (so Jiraiya could break it) on a girl back in pt1 so that she would go flirt with Jiraiya.
Danzo has shown greater mastery of KA than Shasaj and Otachei.
