Well than that is a huge disappointment. Then in all future debates, A should be one handed, Orochimaru with no arms, Hidan should be headless, Kabuto as he was in part 1, Tsunade should be cut in half, etc. Yet, even if Itachi is to be ill and nearly blind he can still defeat Sasori.
All i'm saying is that if we are going to play by the rules of electromagnetism, regular fire techniques and Amaterasu are more than sufficient to make it ineffective. Sand, Gold Sand, and Iron Sand are all Ninja tools that are chakra infused. but they way that they are manipulated is different. In the case of the third kazekage, he uses his magnet release to manipulate the iron sand, thus any amount of sufficient heat neutralizes the iron making it incapable of being manipulated. If not, well then we'll just have to agree to disagree XD
Itachi's low stamina levels only come into play with the use of his mangekyo techniques, as his chakra control, chakra level, clan prowess, and his genius/high intelligence/ aptitude as a prodigy allow him to utilize everything else extremely well. He could sustain and maintain the normal sharingan and mastered it at the age of 8. This takes much more chakra than other techniques.
Again, Itachi being a generational genius, if we are playing by the rules of electromagnetism incorporated into the narutoverse, would be plain to him.
This is like the first time I've really gotten a chance to debate someone, it's been enjoyable! Thanks for including me man
