The most marvelous Ninjutsu of all time.

[Seventh Sama]

It is a very powerful technique.

Though I'm wondering why Naruto's first Sage Art: Lava Style Rasenshuriken had no apparent effect on Son Goku's chakra within Madara.

Because it was meant for cutting. The nine bijuu RS is a bit different.

Marvelous (causing great wonder; extraordinary)
That technique is indeed extraordinary, after all is the first technique that uses all the natures of the bijuu.

 

[Sennin of Logic]

It wouldn't work against Sasuke. Sasuke basically used COAT to perfectly make the bijus one, complete chakra. He wouldn't have lost control.
