and heres a ninja that speaks with words of intellect. you are greatly respected by me, as of from this moment on.....stamina doesnt have any thing to do with learning new moves, because if thats the problem then he just as to train for more time in less hours taking less strain on his energy
and plus sasuke cant learn kakashi's MS technique because its a genetic trait so only kakashi and perhaps obito(because we dont know if its due to kakashi's own chakra traits that kamui was created)
