What makes you think madara who is superior to obito, who taught obito everything he knows, who is a transmigrant, who is more knowledgable can't use the sword of nunoboku???
He claimed to teach him yin yang release but that could just be izanagi that he taught him. Madara's use of kekkai genkai is vastly different from everybody else. It's like saying rsm naruto can use sword of nunoboku. Most likely has something different because he showed no use of it.
And what also makes you think he can't use a country sized SS after displaying a planetary level moukhtun
How is Madara going to use Hashirama's sagemode? People who get mokuton don't automatically start using the same techniques like Hashirama. Madara couldn't use wood human let alone Shinsuusenju. His JJ form mokuton is way stronger than hashirama's but he can't use his Senpou art to create what Hashirama can.
What makes you think he can't use a portal when kaguya, sasuke, momoshiki, obito can open portals, not only that, him having the rinnesharingan, not only that him having both COAT and izanagi???
Kaguya, Obito, and Sasuke's ocular power are specifically known to awaken portals. Madara does not but he has clones that can go in and out of the shadow world, that's as good as it gets for him. Even Hagormoo can't open portals to different worlds, he needed to summon Team 7 with the bijuus to help them escape. So if Hagormoo couldn't do it, he sure as well can't. It makes sense.
Madara can easily use izanagi but COAT is a hagoromoo feat kinda deal. Hagormoo had to use the juubi and the seals he had in his hands to do that.
