Basically destroy his head, and he wont be able to move or do anything. Dust element would pwn him easily. Giant sand burial would crush him. Any type of sealing jutsu would beat him.
what about the 5th mizukages technique that she used in melting sasukes sasunoo, that should ture him to cream right if that mist were to touch his whole body
There are many jutsu that could finish him off :
-Boil Release
-Lava Release
-Amaterasu
-Rasenshuriken
-Seal him in any way
-Maybe Kirin
Hope you don't need me to explain why all of these jutsu would finish him off.
