I was battling a Marth and I did a successful B-air, it was at 24% and I was able to footstool jump off of him immediately since Lucas' spike isn't powerful at low percents. Successful bair at low percent -> don't move once the spike hits -> jump at end frames of bair. I don't know if this has been known, if it's an At or not, but I can see it being useful in certain situations. Also, I have no clue if it works on other characters, other percents, etc. I have a replay of it but I don't have anything to upload it with as of now.
Marth died and had no chance of recovering after the footstool.
P.s. You will have to fast fall the Bair
