Gaara immediately sends our team up top, we break the ceiling with Katon and we head to flight ceiling. Ino links Gaara so he has view of the battlefield and he'll send a bit of his sand to intercept any attacks as well as launch a small offensive.
Gaara is to defend my team.
If any exploding birds come close, Sasuke uses his Chidori Senbon or Eiso or Gaara's intercepts and clips a wing off.
Ino is free whenever to use a Shintenshin. If she sees she can't, she'll keep mindlinking Gaara with sensing. She'll be relaying any helpful info to Sasuke via telepathy.
Battle Phase:
When my team gets close, Sasuke will summon his hawk while Gaara protects said hawk, Sasuke will use Chidori Eiso to destroy any projectiles as well as to kill Deidara or Hanzo(THIS FIGHT WILL BE IN THE AIR). He can use katon variants as well. If Sasuke feels Gaara's sand is faster, he'll ignore the Kuchiyose rule and ride on the sand platform. Gaara will cover Sasuke with his sand and will also look for any helpful opening he can so he can squish them. Aoda can be summoned via Snake Drop to attack Deidara with his immense speed and whatnot.
If Ibuse and Hanzo are on the ground, we deal with Deidara first, then after he's gone, Gaara will use Ino's mindlink to attack via underground squish or above ground squish. Sasuke can fire Katons from the air. My team will never step on the ground, we will fight aerially.
What ifs:
They gas in the air: Gaara covers my team in sand ball and retreats back.
They stay on the ground and/or cave: Gaara hard counters with sand and Sasuke nukes with Katons from above, this will break the ceiling and cause it to collapse on them GG.
