Its interesting to see hypocrites attacking me for using arguments that the manga can support, without the need to see it in manga scans to make valid point. The same people calling me out on "fanfic" end up turning around and make inductive reasoning on why this character has access to do this. It's so funny that they did it recently, stating in a match up, that Madara can use Shin Sūsenju.
Enough of the rambling, I fail to see how Kurama can even solo this match up. Kabuto still has Hashirama's cells inside of him and the manga supports that Kabuto has the ability to manifest cells to access the characters ability. Now with that said, Kabuto already admitted that he doesn't have full intel on Hashirama's abilities but he does witness some abilities through Madara, and the basic knowledge of jutsu everyone knows about.

] jutsu alone should be able to stop a mindless creature, with no defense support, or give some troubling.
The good thing about using Sōma no Kō is that you are able to do a combination and multitask with your "partner". Kabuto's can perform a jutsu while Hashirama cells using Mokuton on top of it, as an example.
A good way to take Kurama out is to Spawn Mokuton on Kurama, Madara of course is going to force Kurama to blow up the terrain then with Kabuto. But Kabuto, on the other hand, can summon a snake to be used as a meat shield. Mokuton simply could of brought out time for a snake to reach Kurama in close quaters. Kurama fires a TBB and Kurama also gets hit in the cross fire. Another Mokuton will catch him in his vulnerability.
Muki Tensei is still a perfect way to level the ground to where they are standing, to change the trajectory of a TBB, before being fired. Even Muki Tensei and Mokuton would make a great combo. Not because Muki Tensei manipulate wood (because it can't) but the very ground that they are standing on can change and shift Kurama and Madara's attack patterns.
The only threat to Kabuto here is a TBB, to which he has many ways to prevent for exploding on him and used against Kurama himself.
