Bad counter. As you stated, it will break through the earth defense.How i performed it
Sasuke starts to build his chakra, channeling it to his right hand, he then makes use of nature manipulation to change the chakra into wind, sasuke retracts his right hand to his left chest area, aiming at the clone he then swings it horizontally in arc from his left chest area to his right side, as the wind is released sasuke then used shape manipulation to form the wind into multiple blades of wind, still using shape manipulation sasuke gathers the multiple blade of wind at one point and forms a scythe which then hits and cut right through the clone, poofing it.
Advantages
Its a very good technique, a swing of the arm, and multiple blades are first released, then it forms into a scythe, which can slice through someone.
Disadvantages
I don't see any disadvantage,(if spot any please let me know)
your counter
A good counter you did, but you'll be damaged from being thrown back by the wind jutsu.
The Speed Rate
I would rate this technique as fast, its just a swing of the arm after multiple blades of wind, eventually a wind scythe is released. Nothing more to it
Next..
( Futon: Shinkūdama ) - Wind Release: Vacuum Bullet
Rank: A
Type: Offensive
Range: Short - Mid
Chakra cost: 30
Damage points: The user will begin sucking in wind which results in drawing in opponents towards them and by kneading with their chakra in their mouth the user then releases the wind chakra in the form of a powerful bullet that blasts the opponent away.
Focus chakra into your mouth, and then take a deep breath inwards. This should pull my clone towards you slightly, and then release the gathered chakra. This should form a powerful bullet that blows him away with great force.
