I've been seeing a lot of assumption that the Sage's tools are gonna be the answer to defeat Madara but that is not the case. Let's take a look at the facts.
First, the gourd only works in conjunction with the other two Sage's tools. The rope which pulls the word soul and the sword that records and cuts the word soul. Without them the gourd can't suck a person's soul, and we know that they are out of reach.
Second, the amber purifying pot can only seal one person at a time and unfortunately it is already occupied by Kinkaku. And even if it is empty, it cannot seal both the Juubi and Madara at the same time because they amount to two beings. Also it is unbelievable for the Sage's tools to be even capable of sealing the Juubi let alone the Juubi Jink, because if it's possible, wouldn't the sage have sealed the Juubi in the pot instead?
I believe that these tools are reintroduced to be used as substitute for Yin Kurama now that Black Zetsu and Madara have taken it.
