Do you have sage Naruto ? Post your ninjas and summons so we can give better advice.

What's your Gaara?.. My extra account is currently running with Minato4th, GaaraKaze and Hinata or Kushina, Windmain ofcourse.. It can do 6 to 7 combos and skills skill usage is great as the windmain resets the cooldown with impestus.. Using it with Serpent summon, but White Snake will do also. Here's the formation:

X - Minato4th - Hinata

X - X - X

Windmain - GaaraKaze - X

---------OR---------

Kushina - Minato4th - X

X - X - X

Windmain - GaaraKaze - X

Skills : Mystery Impestus, Standard ShadowClone, Passive 4th Skill, FlowerGuard or Wind Enhancement (depends on what you want), Shadow Clones for the last passive. :D

With kushina 3 stars i would suggest you to try:

x minato x

x kushina x

x bd gaara shippuuden

With dance of impetus or sand dust, clone standard, low float to high float chase or highfloat to repulse chase, wind dance and multi shadow clone jutsu or *y harem jutsu. about the summon you just need to link it with the chase you selected.
