When you start to play the game you start pressing L + one of the directional buttons towards your opponent. Keep repeating this process until there is little health on your opponent, then keep pressing left + B. Keep repeating this process until you are satisfied.

Right, slanted down right, down, slanted down left, left, left, slanted down left, down, sslanted down right, right, R, L. You must do this as fast as possible and it'll take a few tries. It takes out a fourth to a half of damage and is impossible to evade.
