First, to make pretty well damage in nine tail invasion you need to increase your power. The more power, the more damage.

Second, by looking at these ninjas, you also have Gaara with 4 stars.. I suggest you make this formation:
Kabuto Gaara ***
*** **X Earth Main
Kankuro **X ***

with the earth skills are: 1-3-2-2-2

Gaara's Barrier could increase the wind ninjas attribute to 40%. Thats gonna make a pretty well damage and tanky in the other hand. Saddest part is you dont have Kankuro GNW.
