I want to straighten something up with the base sasuke does not have tsukiyomi because he has ms from what we know it seems like all ms have three techs but tsukiyomi is not one of them it seems wen you get the ms you get a special genjutsu but itachis is referred to as tsukiyomi because of his skill with it jus like shisui has koto whatever the name is shisui used his to control opponents itachi used his to manipulate time thats why they have different titles sasuke skill with the tech isnt on that level thats why he jus refers to it as genjutsu sharingan
