Well, I don't know what summons you have, but a decent lineup for water with the ninjas you have.

This could also be of a bit of a troll team. Especially if you get breakthroughs on TenTen

Something different for you to try out. I would however, recommend that you continue going through the Jin 1 Treasure to get Roshi, and then go into the GNW treasure to get Fuguki.

Fuguki, Roshi, Sailor Sakura, and Water main is a very good combo.
