Wait what sasuke has a teleportation jutsu? did i miss somthing in the manga:shrug:
Sasuke would be at a disadvantage if he goes for a battle of defense,
susanoo costs a hell of alot of chakra while (correct me if im wrong) Gaara's automatic sand defense doesn't cost him any chakra, His sand armor does tho
That's why I said arrow would sneak , Sasuke should sneak attack past defense or Gaara would just keep defending himself
