A video about Robin's impossible Levin to Bronze aerial combos, or at least intended to be impossible by the devs.
If vid was confusing inputs are: Jab, cancel the first frame of the jab with a jump. This will always result with a bronze aerial assuming you did it correctly and are not flicking the stick hard enough to do a smash attack. That will result in Levin to bronze to levin, effectively having nothing happen.
As always, I made this video with no script and probably missed a few small things about the Levin Sword. Please comment and I'll be more than happy to clear up confusions.
