yo,wassup !
to project his eyes into moon,well it has some flaws imo,first,10 tails was sealed using chibaku tense into moon,and if madara takes it out there probably will be no moon left and it will fall apart,plus moon is not always in the sky,so how is he gonna maintain his genjutsu ?
and above all,madara as we saw earlier can suck people into his space/time dimension,just like wat he did to karin and sasuke,so why cant he do the same to naruto or killer bee
