((Doesn't sharingan have a counter function? leafninja said that it used the countering function of the sharingan to reflect a genjutsu back on the original user right?. Isn't it like holding a mirror up to the genjutsu effect, thus the name "Mirror Heaven and Earth change" I'm not copying his genjutsu, but reflecting it back onto him.))
I just edited my post. It uses the counter function to stop the genjutsu and the copy function to learn it and send it back. It makes it fair, cause if just reflected then the move would use almost no chakra and you could just reflect everything back. It's a genjutsu based bloodline Fenrir, thats why it works best with Genjutsu specialists and Ninjutsu specialists.
