It depends on a few things actually, Naruto can go into perfect Sage mode (fused with Ma and Pa) now since he's friends with Kurama now. Naruto and the toads came up with the idea of using a scroll and tags to summon Naruto clones from the toad homeland and as everyone knows summoning is a type of sealing jutsu. When you summon, sealing marks appeared. A good way to destroy Madara would be to destroy the scroll Kabuto used to summon him, or did everyone forget Madara is a summon and destroying the contract scroll releases the summon? Plus "that jutsu" could be a sealing jutsu since new info keeps tying Naruto to sealing jutsus (Minato, Kushina, Jiraiya, Uzumaki clan) so is has a 50% chance of being a sealing jutsu.
Also is was Kurama chakra being filled with lifeforce that cause Naruto's jutsus to be so effective against the white Zetsus. Yamato already pointed out how his wood Was reacting to kurama's chakra and Naruto's clone wasn't in KM when it fought Madara, only normal and Sage Mode. Also we still never saw Naruto fight full power, he wasted a lot of chakra in training, made many shadow clones (splitting his chakra among them), and then start using the chakra Kurama had left. Not to mention Naruto was given chakra from 2-8 Bijuu's and 2-7 Bijuus and Jinchuuriki could have taught him a lot of new jutsus. (note: Kurama took some of the 8 tails chakra when Bee was helping Naruto fight him, go watch the episode and you'll see Kurama absorb a tenticule.). There are to much what if's for me to answer this question so I'll go with tie until we see more of what Naruto possibly recieved from the Bijuus and Jinchuurikis.
