One of the toughest things to accomplish in Super Smash Bros. Melee is a proper recovery from getting knocked off the stage. This problem is even further exacerbated by the dreaded edgeguard: when your opponent grabs the edge for a handful of frames to make you fall right through to your death.
However, there is a way to circumvent their devious efforts to make you plummet. If you perform an ASDI fast fall technique, as showcased in this tutorial video, then you can make it onto the stage without their edgeguard blocking you. While this technique is most useful with Marth or Sheik, it is still useful across the cast.
