I think the author has some misunderstandings about substitution. he treats it like teleportation. but it's really not. it's supposed to be a jutsu with similarities to slight of hand tricks. if everyone could teleport then Narutos Das wouldn't be famous as the yellow flash for teleporting with his seal kunai.
hmm i dont think you understand what substitution jutsu is sigh... switching places with a someone's clone is not substitution jutsu lol.... if that were the case then uchiha sasuke's Rinnegan ability is useless. Since even genin can do it lol....please google or watch the anime the difference between substitution jutsu and uchiha sasuke's Rinnegan substitution. and get your fact straight.
