Analyse it:
Well, it is a fairly easy jutsu to understand. After gathering a sufficient amount of Wind based chakra, one throws it in a direction which is the form of a sphere. The size of a person's head. The sphere acts like a pulling mechanism, pulling small objects towards it. When the objects are pulled within the sphere, it explodes due to immense pressure. It explodes everywhere, except in the direction of the user, which is pretty cool. One can also create several spheres, of smaller size of course.
Advantages:
-Well, it's up to Long range, which is always a plus.
-It can work pretty well against dangerous small weapons (FTG kunai)
-When it explodes, it doesn't send shrapnel in the direction of the user.
Disadvantages:
-Even though it doesn't take long to form, it might be a drag to throw it in a certain direction and the opponent might already take care of the sphere.
-Needs a two turn cool down, and can only be used 3 times.
