You're clueless, lmao. You contradicted yourself twice.
I'm not contradicting myself buddy.
The above paragraph was my my explanation and the next paragraph was to explain what will happen if Madara follows what you have said in your thread. (small shissusenjuu thing)
Sage chakra and SM Jutsu don't require you to be in SM, they just use SM Chakra, Madara could use it but it'd take 30% more chakra on his behalf, and it'd be the exact same size.
Lol, you're proving that you lack knowledge on the manga.
I agree on the Sage chakra part. After all you can go into Sage Mode after gathering Sage chakra.
But How can one use Sage Mode jutsu without being in Sage Mode? LMAO
Hashirama himself went into Sage mode when he used Shinsuusenjuu. Take a Look. Plus he was gathering Sage chakra by joining his hands throughout chapter 621.

In short, Shinsuusenjuu needs Sage chakra, due to which the user goes into Sage mode and hence can use the jutsu. U_U
Now about Naruto using Rasen-Shuriken, If Naruto is in base form, he needs to go in Sage Mode to use the Rasen-shuriken to avoid the chakra needles as well as for a secondary job which needs Sage mode's sensing ability. As shown in current chapter.
But when Naruto is in KCM/BM mode, he doesn't need Sage mode or Sage chakra to use Rasen-Shuriken. Take a look, he isn't in Sage mode.

If you understood what I meant to say, Conditions to be satisfied to gather Sage chakra -> Gathering of Sage chakra -> User goes into Sage Mode.
( Naruto needs to stay still to gather Sage chakra )
( Jiraiya and Hashirama gathers the Sage chakra by focusing it within their joined hands and hence can move in a battle )
Hence Madara cannot use Shinsuusenjuu because he doesn't know how to gather Sage chakra in the first place. Also Sage mode isn't everyone's piece of cake. Having Hashirama's DNA doesn't make you Hashirama himself. Madara is only capable of using the Mokuton Jutsus which Hashirama can do in base form (without Sage mode)
