How you would use it in battle: Drive the enemy into the ground and finish them off while they are dealing with the damage done with the punch. By using electrical based attacks I would cause the enemy to be stunned(lightning surge) and have less chance of dodging or reacting to the punch.
How you would counter it:
Using a punch of equal or greater strength would cause both techniques to cancel each each other out. Or by using my Sharingan (When it's strong enough...), follow the movements and attack the enemies weak points, eg, the legs, to knock them off balance, or by using their momentum against them.
How you perform it (with as much detail as you can):
I make a quick dash at your clone, bringing my arms up to my waist as I do, a similar stance to the one you would learn in Karate. As I reach your clone I drive my right hand into your clone's torso, at the center of the ribcage, and push forward with my feet. I drive my fist down, with your clone on the receiving end of it, and with all the strength I can muster, force your clone into the ground, dealing severe damage to your clones ribcage and causing the ground in the area to crack wide open and tremble.
