@arv993 can you read? I already explained it go back and read it before you make a post. Madara with EMS wouldn't have the power of the senju or the sharingan he uses for his teleportation. It should be obvious that he has replaced his eyes many times if you haven't noticed the chapter/episode where its shown that he has a collection of them. Re-read the chapter where madara explains izanagi. What is the requirement to use it? The power of the senju and uchiha, the power of the six paths. What has nagato had since age 10? The power of the six paths, and he has the rinnegan. Madara in that same battle says the sage created many things with izanagi and among them was the tailed beasts. Many is plural meaning more then one. Suffice it to say the rinnegan is not limited to using it just once and doesn't suffer the draw backs like the sharingan does. Even if it was madara before the rinnegan, if you can use any jutsu by age 10 that means any jutsu. What part of that don't you understand, the any or the jutsu? Jiraiya said he could use any jutsu, not one or two but "any jutsu he wanted since he was 10 yrs old" - jiraiya. Sasuke has beaten all non-sharingan users he has fought thus far, even users of the sharingan(danzo) so your claim is not valid. After he died it was then that madara was able to do as he wished. Get off the sharingan's balls, the rinnegan is what created ninjutsu and the other doujutsu. If it wasn't so important madara wouldn't have wanted it so bad. The rinnegan is a tool of god and can be used to create something out of nothing. Again what is needed to use izanagi, the power of the six paths. Its not an instant win, its powers just far surpass that of the sharingan and its been proven. However again if you re-read the konan vs madara fight you will notice the rinnegan now has six tome and is drawn over the stone cast as if to correct it. This would mean nagato's is not a complete rinnegan and is why madara still has that sharingan in it.
