Why didn't kabuto revived Uchiha Shisui and Uchiha Izuna?? They were very strong uchihas,aren't they? I know their eyes were taken or stolen. But edo tensei can return your back just like it did to Nagato and Itachi. I don't think he wasn't able to find their body cause he was able find those dead body that shocked the world and tobi. So what do you think?
