Re: Chapter 585 Tsukiyomi
As you said: you wouldn't be surprised if he did it. Remember, that was argubably the first time Sasuke was using his EMS (I'm not counting the one where he killed Zetsu with that amaterasu sword thing). I don't think Sasuke really cared at that point whether he was wasting chakra, because he has EMS and there were only a few zetsu clones to deal with, so it would be a perfect opportunity to try out his powers. Again, I did say it could just be an unnamed jutsu.

Also observe how he only says "Amaterasu" once and it's clear that he is refering to both of them at that point. If both of them were using "Tsukyomi", why didn't he write the same thing for them as well?
