How i performed it
Sasuke starts to mold his chakra channeling it towards his hands(both of them), sasuke then uses nature manipulation to tranform the chakra into wind, as he does that he releases the chakra which becomes wind based, his hands are then covered completely with the wind, sasuke legs are then trapped, he uses his left hand which is coated with the wind, to smash the ground that immobilized his, once free, sasuke rushes at you with his right hand retracted and set for a punch to your gut, sasuke hits u and grab a hold of his right hand with his face turning red.
Advantages
It increases the users strength, just as the description says, the user will be able to break the ground with, meaning that if one is hit while this is active, its an instant K.O. It suits taijutsu users very well.
Disadvantages
It requires close combat like I said its best for taijutsu users, but the user is then open to all range attack, once their in close range, the user can be struck with a nagashi and wouldn't be able to defend, cause he is close and his hands are full of chakra, going out of range would be difficult also would grabbing his sword to redirect the chidori nagashi.
your counter
Its very effective and efficient , a very good one, cause following your counter jutsu description it can block up to A rank ninjutsu techs, and this jutsu is a b rank. Thus making it ineffective, but following this jutsu's description then it still wouldn't be able to break through your earth shield why?, cause the normal ground Isn't containing chakra, making it atleast a d rank earth allowing this jutsu to shatter it, but your earth shield contains chakra and not just chakra but a highly advancd form of chakra, hence allowing this jutsu to not affect it.
The Speed Rate
Fast, its very fast of you ask me, all to do is focus chakra to your hands and after nature manipulation, it forms wind(similar to chidori don't you think?)
