That was not Izanagi LOL are you slow? He had both eyes when he fought Konan, and used Izanagi then.
Without Danzo, he wouldn't have even known how to use Izanagi. He copied it from Danzo, and that fight was way after Sasuke's amaterasu.
I'm slow?

Actually, Madara taught Obito the Uchiha kinjutsu, Izanagi, so you're wrong on that account.
If you use your brain, you might be able to remember, Obito had a collection of sharingan, in his lab. This means, losing eyes was not a problem at all, as he could simply replace it with another eye. He didn't copy anything.
Where are you getting these false claims from? Damn, you used to be a funny troll, now it seems you've gone full on retarded.
