THIS THE LIST WHY I Assume Yata and Totsuka statements to be hyperbole:
1) Third Databook came long time ago, and could be actually outdated. It is even further support my claim as Kishi has made Databook after some time which means that this Databook is completly true to THIS MOMENT..., however it can change.
2) Obvious Hyperbole as Kishi was always hyping Techniques, weapons etc... only to get even bigger attention of fans.
3) Yata Mirror was tested only against weak attack on currently power level of manga(It could be great before... but now no more.), so it lacks feats against such attack as Tailed beast bomb, Amaterasu. Actually Kishi proving it against Onmyoudon could close any speculations and prove it if he want. However it doesn't look like that.
4) Kishi could have changed his mind many times while manga is still going. Basically Kishi wouldn't even think about attacks like Dust release, Tailed beast bomb, Omyoudon etc. WHEN he stated for Yata to be invincible...
5) The most often mistake made by people is basing on Databook after something new is introduced, this is not how databook works. Databook only confirm and make clear about statements, hype and deliver some explanations about things which happened in The manga UNTIL NOW/SO FAR. Simple Databook is used to close some period of manga clearing all doubts, but it doesn't work like it should be used to explain future as future changes constantly and anything new introduced by the manga can be only proved/disproved by the manga.
6) EDO Madara was stated to have no weakness in Kishi's interview could it mean, then what if Totsuka will be used against him ?
Contradiction, my dear buddies
Simple Yata Mirror is invincible weapon which can defend any attack introduced in the manga to point when Itachi's died, same with Totsuka Blade being capable of piercing through anything to the point when Itachi died.
Anything before is includd in that statement/hype but anything from future can be or not, it depends from the manga.
