So the first technique requires a fan or the use of a large amount of hand seals. You blow out wind or swing the fan and it takes the form of a net. The net can pretty much slice through anything a-rank wind can on the strengths and weaknesses. This is the one temari used against the Sandaime Raikage right?
Second technique is just a basic fuuton Danzo used against Sasuke. Move your hands, and multiple blades of wind form a scythe that continue towards the opponent at good speeds. It was strong enough to stop a Susano'o, but not cut through the defenses.
This technique is interesting. You inhale a bunch of air that pulls the opponent in towards you, then you release it as they come towards you to blow them backwards. Seems relatively fast and efficient.
