This reminds me though. I remember someone comboing a Spin attack into a meteor dair by grabbing the ledge with the spin attack and then acting out of the ledge grab in time. Or at least that's what it looked like. I believe it was Kirinblaze who did it in one of the vids he uploaded. Is it a true combo? I also remember being able to combo an incomplete spin attack into a ledge get-up attack pretty consistantly by accident in a similar manner.
I know this may have been discussed already, but how viable are Zair confirms? Last I remember, Zair can true combo into Dsmash, though for whatever reason you can't buffer one out of Zair, making the combo a little difficult. Not to mention that your opponent can DI out of the combo at higher %s. It's still very doable, however. I'm also aware of the other follow-ups that are possible. But is RAR Bair one of them? Arrow confirms out of Zair seem like they may be the most guaranteed option since it's a projectile that travels forward pretty quickly and has low startup, but I could be wrong.
Lastly, I don't see anyone using tether cancels to mix up their recoveries at all in your replays. Like, why? I see so many situations where you guys lose a stock or even the game due to being gimped whereas it could've easily been avoided by tether canceling (or hell, you could've used a tether cancel to retaliate and end up gimping your opponent instead). It makes me cringe whenever it happens. Seriously. Tether canceling. Use it, it's awesome. Enough said.
