So, I'm very new to Lucario, but I stumbled upon a really sneaky stage spike set up that I find really fun. I don't know if it's an extremely viable technique, but I'd like to share regardless. It works on any stage with angled ledges like PS2, Smashville or Battlefield.
So it's grounded UpB horizontally across the stage >ASC right off the edge>Nair (opponent should be stage spiked trying to return to it, or occasional gimped the opposite way)> Then UpB to recover. Easy Peasy.
Also, since your opponent could possible ledge tech, it might be that you could also cancel the Nair into another aerial to trap them under the ledge.
It should be noted I haven't tried against any character who wasn't a fastfaller, but if anyone wants to do some more experimenting please feel free to add to this.
