Fire and Earth require a coupon tier ninja to make a decent team so I'd suggest you stay away from them for now. A decent team you could use for water is this:

Darui, TenTen, Mabui

x,x,x

Watermain, Water main clone, x,

Talents/Summon: 3,2,3, 1 or 2, 1 Lightning Tiger

This team works decently, although I'd suggest you to stay with lightmain and use the kushimaru, jinpachi, and sasori team.
