@Prince Charles, the soul dragon is countered pretty easily with his versatile Mokuton, which can be used as a shield of trees surrounding him. Before the argument of the dragon being an immaterial entity appears, one should keep in mind that the dragon stroke into the ground instead of slipping through it when Hanzou escaped with Shunshin no Jutsu. All Nagato will do with this technique is crippling himself like he did back then. While he is connected to the Mazou, he has no mobility and becomes an easy target for Hashirama, who will use the Mayfly technique to disappear within the surroundings and use techniques from there. He can also send Mokuton Bunshins with the Mayfly technique to Nagato, who is immobile at this point to crush him with one of his many possibilities.
Gedo Mazo is easily eliminated with Sage Art: Gate of the Great God.
I mean do you not see hanzo subordinates falling out the soul dragon[

Obviously you're underestimating the gedo. That fact that you believe it get restrained that easily via mukoton is quite amusing. You don't even take into consideration of the Gedo's mobility[

Not too mention its firepower you decided to completely ignore you clown. It's chakra shockwave and its chakra blast will easily be able to counter the mukoton surrounding it. The shockwave covers a 360 degree angle around the Gedo which would obliterate the mukoton[

]. The shock wave covers a large radius surround the gedo, the majority of the mukoton will be gone thus the gedo be loosened from captivity. The chakra blasts will have no problem destroying the mukoton.
Don't even bring up hashiramas wood summoning's. The vast majority of them can be handled by the Gedo with its chakra blast[

The shockwave from the gedo can potentially destroy some of the gates from hashirama. Not too mention I see no reason why he simply can't re summon the Gedo out of the torii seals from hashirama
