Re: Can only Nagato use that jutsu!?
I am going to go out on a limb here and say I don't think that technique can be used ANYMORE. Since the Gedo Mazo transformed into the Juubi, I don't think it is any longer the Gedo Mazo, since the Gedo Mazo was just an empty vessel which became full and once again transformed to the Juubi.
In essence, I do think Madara and/or Obito would be able to use the technique, but something tells me both Madara and Obito knew it wouldn't work against Naruto + Gang, or it would be a waste of time/chakra/trying, etc...
Also, Hanzo dodges it with a simple Body-Flicker Tech./Shunshin No Jutsu:
