@darkraiden Totsuka Blade is not physical, and as such physical durability does not count. Remember, these items have been called god items. The two times we have seen it used, it has pierced its targets indefinitely. Never have we seen the blade take physical form, although it has been extended in the shape of a sword in both instances it was used.
About Yata Mirror, since I dont have access to the source, I can only speculate that the alterations by the Yata Mirror can only happen within the limits of the embued nature transformations, that is the many nature transformations however it may come. Lantern Rings power comes from a different source that is not entirely natural. The power comes from an almost mystical source. Formless chakra manipulation without any nature transformation such as Genjutsu and Fuuinjutsu has never seen meeting with Yata Mirror and being repelled. In fact, in application, Itachi has only once used it. He didnt even use after being resurrected.
Allow me one last chance to change your mind. I have a full scan of how Yata Mirror and Totsuka blade work. Please let me know if anything else is unclear (read from right to left, obviously).
Itachi is more than well-equipped for this battle.
Oh and @darkraiden, (and I guess @superbot400 as well) as I mentioned earlier durability isn't a valid argument. (as stated above) Totsuka is imbued with a sealing jutsu. Strength of the pierce is not a factor. Physicality is not a factor. The blade itself is not physical, it is a spiritual weapon (more close to astral--can "pierce" anything) with a sealing jutsu attached.
Durability from the GL is not in the question of whether Itachi can seal them or not. Speed (Itachi's ability, or lack thereof, to catch them) of the GL is.
Only scan I found that says Izanagi is active only for the briefest of moments, nothing that says Senju blood is a requirement. Danzous Senju DNA allowed him to use Izanagi with a single Sharingan for 60 seconds, and Obito managed to use one for 10 minutes. Itachi used Izanami that had the same consequences of using the jutsu as Izanagi, and even as Edo (with regenerative powers), still lost his eye sight. Find me a scan that says you need Senju blood to use Izanagi, or a source document which says so. Because through the reserches I have carried out, I did not come across such information.
About Yata Mirror, could you please cite the source, link it perhaps? Because from all the wikias that I have read, all of them states Yata Mirror as being embued with Nature Transformations, allowing it to repel almost any ninjutsu, because most of the ninjutsu uses Nature transformations, as with your explosive tag example, fire is a Nature transformation. Explosive tags have Fire sealed in them to exponentially let them out in the form of explosions.

*sigh* I see you didnt read my previous comments all the way through. I already sent you these scans.
I don't have the databook in my possession. But it is found in the Third Naruto Databook on pages 274 and 275.
If you look at the Narutopedia (however credible it may be) it says it is endowed with all nature transformations but that it alters its properties to negate the properties of the any attack.
