Squirtle's AT nomenclature makes no goddamn sense so I'd advise you don't get your inspiration from those guys.
I mean the shell shift/shell stall stuff is logical, because Squirtle is the only character to have those mechanics, but all the hydroFtilt and itemplane stuff is just namecalling at its finest.
Edge canceling is not a Ganon exclusive mechanic, and having a name just for that is like the Arty vortex, it's confusing for anyone who haven't seen the original post where one guy said "let's all agree that from now on we will call 'X' Y". If you want to be confusing then go full ECAWK (which when pronounced out loud sounds a lot like e-**** lmao), but personally, when I write something technical I like the idea that everyone can understand what I'm saying, even people that don't main the character.
Soooooooooooooooo, now that I'm over with that rant let the dumping begin :
-Air to Ground Flame Choke (ATGFC for GeZ lmao) :
A lot of people already knows this but I'll go into it one more time : when you're at the ledge and start a Flame Choke offstage and direct it towards the stage, and you're at the right height (more or less Ganon's knees must be at ground level) when Ganon lunges forward you will perform a grounded Flame Choke that will have the effect of the air Flame Choke.
So you get both the advantages from the grounded version (longer reach, faster displacement and lower cooldown) and the air version (guaranteed follow ups) which makes the move even stronger than it is. It's not the ultimate weapon when coming back on stage, but when added to the other options it gives you some crazy mixup potential.
It will also work on slants if you have the right spacing.
Fun fact : Falcon has something similar with his side B, but it's harder to do and it doesn't give him the meteor effect.
-Autocancels :
It's already been covered a bit with the Nair cancel talk but you must not forget that all of Ganon's aerials autocancel from a short hop. Autocanceling means 0 lag, like an empty short hop.
Aerials that can be SHFF autocanceled (SHFFAC ?) : Nair Bair Uair
Aerials that can't be fast fallen : Fair Dair
Imo the AC timings are as important to learn as L canceling.
-The chin Meteor :
Ganon's Dair hits everyone from everywhere. His face has a hitbox, it can hit tall opponents through platforms from above and on top of that the hitstun is massive. Dair is love, Dair is life.
That's it from the top of my head, maybe I'll find some more later.
