first up, sasuke's tsukuyomi cannot manipulate time (at least that's how it was with MS)
second, you need sanju DNA for izanagi,
third, the eye that uses izanagi gets blind.
so let's say that he got itachi's tsukuyomi and tobi gave him some of hashirama's DNA,
sasuke: I showed you true power...
naruto: naruto where the hell are you looking I'm over here.
sasuke: wtf is going on? turn on the lights...
This....
last time i check izanagi need senju DNA
and this...
Even if Izanagi managed to not close his eye. It consumes a vast amount of chakra as does Tsukuyomi.
This is another total speculation thread. Making more fanboys act as if this is the truth.
Sasuke cannot and will not manage a Tsukuyomi/Izanagi of that Magnidude. He is great with the powers he has but has never used Izanagi and doesn't have the DNA required nor has he ever been shown how to use this skill or to have any understanding of it's use. Tsukuyomi,only affects one person and Sasuke's Tsukuyomi,as far as we know,still sucks.
Please just stop coming out with these terrible threads which couldn't hold water as well as a siv.
Holes in theory which mean you shouldn't have made it.
1: Sasuke doesn't know Izanagi...

2: Sasuke's Tsukuyomi isn't great.
3: Sasuke lacks Senju DNA. Which is needed for Izanagi.
4: Sasuke doesn't have the Rinnegan and we don't know if Rinnegan requires Senju DNA yet.
5: We don't even know if Tsukuyomi could be mixed with anything else.
6: Rinnegan doesn't allow either the use of Tsukuyomi or Izanagi.
