The kid who said Naruto can beat Obito seems to forget that Naruto can't even touch him.
Anyway, Naruto's clones are easily taken care of in CQC by the Gunbai just like they were in this scan.

Obito can easily suppress Naruto's Bijuu powers once he enters the Full Kurama Cloak using Outer Path's stakes. Thus staying in KM lvl 2 is the only way he will be able to fight him, but if he does that he gets destroyed by Gedo Mazo. Rasengan and variants are phased through or reflected with the Gunbai,
BM either runs out or Obito warps him or takes his soul with Human Path.
