i learned quite fast to just learn "conclusion" in your threads.. sorry if you had theory about this too and if you did copy-paste-it i like to see if it's solid
mangekyo sharingan first itachi awakened it and he do have tsukyomi and after theyr battle sasuke first awaken his own mangekyo which is very similar to itachi's "danzo quote: you have same eyes but how you perceive things are very different"
after that sasuke implanted itachi's eyes to himself right? if you take someone's eyes you take ocular power of them too, so sasuke do have tsukyomi for sure even if his genjutsu is "sharingan genjutsu" suited for taming he have itachi's jutsus too, that how ems works...
