during naruto's training to develop rasen shuriken, kakashi mentioned that jonin-class ninja can use up to 2 basic elements. he also mentioned that if someone doesn't have affiliation with certain element, it's useless to train for the jutsu in that particular element. yet, we've seen kakashi copying almost all element perfectly. so, how did he do that?
