Marth Tech: Drop Cancel
Description / How To Perform
If you fall through a platform, and instantly use a fair that hits either an opponent or their shield, you will cancel the drop through the platform and land back on it. With an L-Cancel this allows you to followup very quickly. This could potentially be repeated for strong shield pressure.
This tech can also be performed with a single hit Nair but is much more difficult to time correctly.
Usefulness: (Generally Useful)
The timing window for the fair is only a single frame, but attempting it and failing will usually result in a regular drop-through fair, which isn't a bad option regardless.
