Facepalm... am I the only one who read the manga?
Actually Sasuke has used Tsukuyomi against Killer Bee and Danzo however he sucks at using it.I read the manga too, and you have no common sense. Sasuke has 3 ms techs, blaze release, Amaterasu and susanoo. He hasn't used tsukuyomi. Madara hasn't used Amaterasu or tsukuyomi. If obito has his other eye he will have a third technique and it might've been susanoo
