@LHDL, it's all about timing, make sure you hold down for an ample amount of time before you jump and push B
@Pillaring Sheik and Ganon: Uhh, I don't see how waveshining is involved in pillaring
@Peach Problems: Lock her down with laser, aim to outcamp her
@Playing Smart: Be controlled chaos, do fast moves to keep the pressure on but don't blindly throw yourself into a shield, keep an eye on how your opponent reacts to any action you take.
For example, if you know that your opponent deals with lasers by full jumping over them and approaching you, keep that in mind for next time, and the moment he jumps jump up with him and d-air his face in.
