Koto is restricted in this battle.

Obito has the Sharingan and the prowess of Madara in life. His predictive abilities would make it massively difficult for Itachi to manage Tsukuyomi, especially with its wind-up. Also, Obito has the ability to put Jinjuurikis in Genjutsu for extended periods. His skill with Genjutsu is very high as well.

Kamui counters Susanoo by making it unable to hit him even though it's a huge chakra drain on his opponents. Also Shisui does not have Susanoo. It's game only. We only use game only techs if OP specifies.

If Obito warped one in, he could just warp himself to Kamui too. Either kill or Genjutsu the victim, then go back out for the other one.

Unless you think either Itachi or Shisui could each take on the team of Bee, Gyuuki, Kurama, Naruto, Kakashi, and Guy all at once. Because Obito did that.
