Marth Tech: No-Impact Land
Description / How To Perform
You can remove the landing lag from landing on a surface by performing a No-Impact Land. A NIL is performed by timing your jump such that the center of your character is roughly even with the center of a surface at the apex of your jump. If timed correctly, you will instantly stand up instead of experiencing landing lag.
Difficulty: 
(Advanced)
Usefulness: (Occasionally Useful)
Extra Info
Doing a NIL saves allows you to act three frames before a regular land, since regular landing lag is 4 frames.
An interesting advantage of this for recovering from the edge is that your opponent wont get the visual cue of the "white smoke" when you initially land on the stage, potentially making them react slower.
