I would go with deidara
Deidara have doton, that overpowers suiton (kisame water jutsus)
Deidara also have his clay bombs, wich i dont know if it would work underwater, but since Deidara is a long range fighter, i dont think Kisame would lay a finger on him
If C3 doesn't work, the nano bombs Deidara uses with C4 rapes Kisame
Unless, as someone previously said, water makes clay useless
