Is there a guide to all that somewhere?
Well, there's a text guide written by the Zard Skype Chat that goes over some of the new AT's but we haven't written the full section yet because school caught up with us. :/

Main stuff to consider is definitely glide canceling, both B reversing and wave bouncing. Both are useful for recovery mixups and for combos as well.
Other stuff to consider is using Glair (glide attack) to waveland onto platforms (abbreviated GLanding). You can practice this by standing under the platform, short hop, glide immediately, wait just a moment, then Glair. You should waveland onto the platform above you with quite a bit of horizontal momentum.
Shield dropping is also amazing since it makes your platform game that much stronger, but that's something that is really really hard to explain so I would recommend looking up a guide on how to do it.
Glide camping is super useful too, just look in the ledge section of the guide and you should find out what I'm talking about.
Oh also, you can just Flame thrower to instantly grab the ledge, though it is quite situational. Roll into the ledge so that your back is facing the ledge and you're as close as possible to the ledge. Just press B and you should fall right to the ledge.
You can also dash attack the ledge, then hold into the stage and after the dash attack finishes, you'll turn around and fall to the ledge.
Probably the last thing to learn is Bair wave landing. Short hop Bair has a cool thing about it that if you don't fast fall it, the end lag of Bair will make it so it is super easy to perfect waveland (waveland on the ground with your analog stick perfectly to the left or right), because right as you finish the Bair, you'll have like 2 frames to perfect waveland so the timing works out quite nice (as well as Bair makes your model waveland more easily so perfect wave landing is much easier).
Other than that there isn't much else, just work on RAR Nair, Ftilt spacing, and jab anti airs and you should be good to go. Let me know if you have any questions! :D
