Sorry, I don't know what's the name of the technique Madara used in the last episode... but he used it with his Susanoo... so Sasuke can or can't learn it? What's your opinion?
No He cannot use it. He needs powerful chakra and Rinnegan.Why?
It is because Madara used bansho tenin on a high level to attract that meteor or he summoned it.Summoning something that large consumes a lot of chakra
