Current Team Taka without Oro vs Healthy Itachi.
Current Sasuke, Juugo, Karin, Suigetsu vs Healthy Itachi
I read some response and noticed that many people either overrated Itachi or underrated Taka. There are a few things they seem to forget. One, Tsukuyomi doesn't kill, this is supported by the manga when Sasuke was hit with it Zetsu questioned why Sasuke wasn't on the ground and not why Sasuke wasn't dead. Tsukuyomi is to cause the victim to be unable to fight by the torture that Itachi displays. This torture can be mental pain like he did to Sasuke in part 1 or physical like he did to Kakashi. Each use of a MS jutsu causes pain to the user so that leaves an opening to be attacked as well. Next is Itachi's blade, it only seals when it pierces the target, this means stabbing them. This is shown when Itachi first used the sword. When he slashed Orochimaru snake's head, they weren't being sealed but when he impaled him then it sealed him. Same with Nagato.
As for the Itachi blade being instant, it's not. Sasuke also has his own blade to block Itachi attention to seal him so it will be a sword fight amongst Susanoo. Sasuke can use leg susanoo which is faster and able to manuver way better than V4 so it wouldn't be easy. Yes Itachi has a sword and shield to cover both sides but the thing everyone over looks is the pain Susanoo cause to a MS user. Sasuke described it as every cell in his body (this was during the Kage summit) so Itachi wouldn't be able to substain Susanoo for long and Sasuke can stop Itachi blade with his own.
Someone mentioned that Itachi would Tsukuyomi Taka but that would only hurt Itachi. Using 3 MS was his limit alive so if only Suigetsui, Karin and Juugo then they would be in physical pain like Kakashi was in but you have to take in their abilities. Suigetsui body is water but we don't know if his body would be water in his mind so if it is then what torture would Itachi use on him? Juugo took hits from A and was still coming and we know SM has a recovery rate increase so the senjutsus he uses might be what helps him. Also they could just bite Karin and heal themselves.
If Itachi uses Tsukuyomi on Sasuke then Sasuke would just break out. If he can do it with 3 tomoes and his CM then he can do it with MS or EMS. Itachi recieved painfully feedback when Sasuke broke out so that would just further weaken him. Sasuke can match enton to Amaterasu as well. All in all, Sasuke just has to keep pushing Itachi to use his MS which would just wear him out with its side effects and chakra taxing so Sasuke with EMS has this even if the other Taka members dies.
