If it's not Isuzu-chan Mii~
I posted before that Sasuke is far from Itachi's level of genjutsu. Sasuke visibly staggering after it was one of the reasons why I formed that opinion.
Well, his eyes turned into his Mangekyou when he used it on that Cloud ninja when he was looking for Bee. Since Mangekyou makes you go blind, I don't imagine he'd activate them if he didn't have to to use whatever Genjutsu he was using on the guy. I can't remember if he said Tsukiyomi or not at that time.
