Edge-canceled Aerial Wiz Kicks (EcAWK for short)
Pretty much just aerial wiz kick onto a ledge and, if you're close enough, you'll slide off the ledge and cancel all the lag you would have experienced from landing on the ground. From what I've found, there are several ways you can apply this.
(1) You can combo with it if your opponent is standing on or very close to a ledge. It'll pop them up with the landing hitbox for you to smack in the face with just about any aerial (this is devastating if the person is popped out over the edge of the stage as it sets up for a f-air close to the blast zone on some stages). This, however, is a bit situational.
(2) You can edge guard with it. If your opponent isn't that good at sweet spotting ledges and doesn't have a recovery that sticks through the ledge too much, you can aerial wiz kick into the ledge and spike him. However, this is even more situational than the last application.
(3) You can use the EcAWK much like you would a waveland on/off a platform. Except, when you do it this way, you can do it from far above the platform/edge and have a spiking hitbox on your leg (this technique would be way better if he actually had a hit box on his foot). I've tested it on every platform on competitive stages and have found that you can put out any aerial before you hit the ground after edge-canceling it (the exception being d-air from Yoshi's Story lower platforms).
(4) STYLE. You can repeatedly edge cancel aerial wiz kicks on the same ledge by simply jumping backward and wiz kicking into the same ledge again. In fact, on Yoshi's Story, you can EcAWK into every platform edge without touching the ground normally (I spent a good part of an hour testing these things yesterday). On Yoshi's Story, PS2, PS1, Lylat Cruise, FoD, WarioWare, and a few other stages you can go from ledge to ledge on the same platform over and over.
Still trying to come up with a catchy name. EcAWK just won't do... Maybe "Edge Kicking"?
