I'm surprised there was nothing for Water Main! So I'll provide one in case people are interested

Well idk how good this line up will be but.

Toroi Pakura x
Water Main Sage Naruto x
x x x

Talents: 3 2 1 3 2
Summon: Gamaken/Gamachu

Now you can swap Pakura with Sage Naruto in positions if you choose to, doesn't really matter. You have Immobile, Paralyze and great healing and great damage. Over all on paper this team looks good but in practice it may need a bit of tweaking. Pakura gives Sage Naruto and his clone an extra standard so that's cool. When she crits she immobiles units affected. Sadly her Mystery is really off having a Battlefield CD of 2 and a normal CD of 2 and her chase always crits.

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.
