A combo I stumbled upon that I haven't seen anyone else perform (a potential Ryu'ish 0-to-Death).

[Mini_Mac]

I was in training mode practicing my jab lock tech as Mac. The combo I was practicing was Dtilt -> Nair -> Footstool -> Dair
-> Usmash... However, by accident, instead of doing a Usmash to finish off the combo, I did another Dtilt instead and I noticed that the distance that my opponent flew upwards was relativley the same. After I stumbled upon this, I repeated the combo after the Dair and then I repeated it one last time. The most I pulled this off in training mode on the CPU without messing up was 3 times and I finished it with a Usmash.
Who else is aware of this combo cause I have never seen it in tournaments or FG.

footstool combos are awesome but they are not guaranteed accept on heavies at strict percents and even then you have to read the DI with d-airs tiny hitbox.

Little mac does have a true 0% to death on fast fallers like Sheik and Falcon

Back of U-tilt turn around D-tilt D-tilt step forward D-tilt KO Punch

i really do wish footstool combos were true, it could lead to crazy shenanigans like dtilt/nair/foostool/dair lock then rinse repeat. Still can be a useful combo on unsuspecting opponents.

dair is just too shortranged and not sexed enough to make it reliable. most importantly nair has no guaranteed followups (including footstool) until high ranges and only with a sweetspot glove hitbox.
