Spoiler warning, latest manga chapter discussion

First I wanna say that the meaning of an ultimate lethal attack is beginning to vanish for me since the Raikage and Jugo keeps standing up after the attacks on each other. So I think that that part is bad.
Darui's sword looks familiar. Fantasy running out from the author when he can't create any more unique looking swords?
Sasuke's genjutsu, was it used with mangekyo sharingan? Just thinking since he was holding his hand in front of his left eye afterwards.
Tobi's story sounds familiar, doesn't it? From other manga which I have read, about two possible heroes to save the world. The other one with love and mercy and the later with might and domination.
