He can work with Water Main. Especially if you run Darui cause Darui's barrier buffs Water and Lightning. So you could run something like Water Main, Darui, Toroi, Ameyuri Ringo. Or if you want to step away from Ameyuri Ringo you can run Edo Zabuza. Just need to get creative. But if you were to run GNW tenten you can run mabui...but that would make you lose Toroi or Darui.
