Early on you c*e Team 7 or go for Karin, Kurenai and Hinata and run an empress team.
Later on look for ninjas like Conference Temari, GNW Kankuro, Gaara.
If you plan on spending you can eye up ninjas such as Sage Naruto, Kazekage Gaara.
Early game the ninjas aren't so key but later on, with the game at the current stage you will want to look towards wind nature teams as you'll get better results from them. There are some exceptions with this such as the Mei empress team with Mei Terumi, Mabui and Playboy Sasuke.
