Genjutsu on naruto= useless since genjutsu on a fully trained jinjuriki cant work and the strongest gen he knows not is tskukyomi
Amatarasu on naruto= too slow for bm and nine tailed regen troll
susano'o= tailed beast rasengan or sage art multi shadow clone massive rasengan barrage
susano'o arrow= BM is dodging this
EMS= all this does is gives him the ability to troll certain jutsu, charkra is still getting used remember
RIGHT NOW he hasnt got eternal so susano'o is asting unessasary charkra so as gai tries not to get hit with any jutsu (not saying he wont get hit) sasukes charkra depleates 2 fold since susano'o is activated AND hes using additional charkra for other jutsu
