There's a lot to be added to this.
First, yes, Finns7 video does a good job of showing how you might use uair out of a wizards foot, but there are so many options out of a canceled wizard kick and that's just one of them. It's good to know and practice all the options you have because your enemy won't always be in good position to use uair.
You can use:
- Uair
- Rising Uair (see Finns7' video)
- Dair
- Rising Dair
- Fair
- Rising Fair
- Reverse Bair (I believe)
- Nair
- Rising Nair
It's important to know that regardless of the move you choose, you have
exactly the following: time for one aerial, one jump, and one recovery. I suppose one might be able to do a uair, jumping second uair in the direction of the platform, and still sweetspot the edge with up+B, but I don't think that you can do two aerials with any other move and still make it back...maybe Nair.
In general, the "rising" moves are much better, because your opponent will almost always be sent at an upwards angle. A really disgusting move is to jump back towards the stage out of the wiz cancel and do a fair while moving towards the stage, but fairing away from the stage. Up+B to recover after smashing face with the fair. And as we all know, fair covers a nice bit of range as your rising/falling.
At lower percentages you might consider a well timed rising dair, as your opponent will have significantly less knock back which means you might be able to get over them. With a big guy like Bowser or DK, you can put that disjointed hitbox to work.
Rising Nair is a great option generally because it sets up a "wall" of sorts. That is, it covers a lot of vertical real estate and stays out for a long time, so if you land one hit, you might be able to sweetspot the ledge with an up+B and get off the ledge in time to finish the job before your opponent is back on the stage. Or maybe you just edge hog.
Okay, I'm sure it's becoming obvious at this point that there are a seemingly infinite number of options that you can do here. As I said - and it bears repeating - you need to know all of them, the ground they can cover, and the situations in which they are especially salient. Furthermore, you need to know how to read the knockback of your opponent so you can make the right choice. 9/10 times you'll miss the hit if you wiz kick thinking "alright, all I gotta do is uair outta this and...s***, he spiked me."
Here's the order of priority in doing this "sequence" (we'll call it sequence as it's not really a combo).
- Land the wizard foot and watch for the roll out animation to begin
- While waiting for the roll out, note the knockback trajectory of your opponent.
- Once you've read your opponents flight, and the roll out animation begins, buffer it with a SMART choice to either: jump, jump towards the stage, or fall towards the stage
- Now that you're flying (or falling) in one of 3 directions, make your move. The most important move is: "survive". That means, if you're going to get spiked trying to meteor smash someone, reassess what you're doing, and make the right choice. Remember air-dodging? Use it if you have to. Bail out if you have to. Defense comes first, landing a follow-up hit plays second fiddle. If you're a good ganon, you'll never be short of KO opportunities...never force a single one.
- If at this point you think you can get that hit, DO IT. Don't hesitate, just do it, and make them pay! And love every moment of it because they're probably dead.
- Sweetspot the ledge. ALWAYS sweetspot the ledge (as a general rule of thumb, not just in this sequence).
Got it? When you're over the ledge you should be thinking first and foremost: stay focused, this one isn't a shoe-in. Don't be stupid, don't die. All of the thinking I wrote in the list above has to happen over about a second and a half, maybe 2 seconds...so obviously, you have to get a feel for this process. You'll eventually know what works and what doesn't...so just practice. As always with Ganon, don't burn yourself by being reckless...wait for it and punish. You're a nasty M f***er. You know that, now make them know it.
