Are you kidding me ??LOL if he cast Izanagi with the other eye that means only Kamui eye left right?
Nothing stopping Itachi from using Faint clone explosion or ANOTHER clone replacement
Try again
Dude , if Obito uses Izanagi he can stab Itachi at no time , furthermore , Kamui's speed is faster than Jinton's speed . Just deal with it , Obito > Itachi .
