Lmao why are you saying Minato can't warp Juubi's Bijuudama while alive then when he actually did it in the manga?
Did you even bother looking at the panel where Obito explains it? It was the mini-FB of the first genjutsu attempt on Danzo. So he was referring to that obviously and at that moment he had no problem in chakra. You're just continuing to make excuses
And we have never seen Minato getting caught by a genjutsu, so why do you think he would be? If elite and even some genin ninjas(Sakura or Shikamaru) knows how to break genjutsu(with kai release), you really think a Kage level can't?
