Well first you should consider changing to another character; From the current ninjas you have i would recommend switching to Wind main.

For starter you can try the below lineup. Talents : 3-3-4-3-4 (Dog of Hell) . You c*so try the 3-3-4-4-4 since that passive will recover life 2x each round.

Actually this formation works better with (Flood Dragon) summon but since you dont have him yet; still Dog of hell will be decent enough with this lineup

Also you can try other wind lineups to change Gakido with Temari Five Kage Summit or GNW Kankuro
