LOOOOOL I had no idea that existed, that is not me.
It's kind of tricky, but I pretty much use them whenever I want to jab but they're a little far away, or to stuff approaches (angled up ftilt on Jigglypuff coming in with bairs, for example). The down-angled ftilt can edgeguard some characters easily as well.
You can also use them to help put up a wall, using auto canceled nairs into a jab, dtilt, or ftilt, though it's most effective against close-ranged characters that like to approach and try to punish you.
Arty's sort of "the guy" for this.
Another thing you could look into is perfect wavelands. It looked like you didn't get very much distance off of your wavelands (if that was intentional then disregard this
). The timing is really lenient on Ganon compared to other characters for perfect wavelands (wavedash completely horizontally on a platform/the ground), and you can get a lot of movement that people don't expect out of it.
You can also sh bair/upair > perfect waveland as a spacing tool, the timing is relatively easy once you get it under your fingers. You can throw out bairs and waveland away to be more cautious, or waveland in and put on the pressure.
It occurred to me that you probably ought to post those in the Ganon video critique thread if you want advice from more people
