I don't mean this to come off as snappy, but day 1 tech or not, it's powerful, worthy of discussion, not being discussed and not being used by players on video. If there are people applying it, I've never seen them and none of the big name players are among them, judging by their videos. If you can give examples of people using it I'd be interested to see it.
Go ahead and share your thoughts. Your video was a very good introduction. I think you should have also included the point that you can teleport through platforms while standing on them by falling or jumping and then teleporting(JC teleport; you just need to be in the opening frames of your jump, I believe); otherwise M2 just teleports forward. Bringing up its potential use in combos would also be good(simple ex: dtilt>uair>teleport DF>utilt or double teleports using platforms to connect otherwise impossible combos/strings, like maybe fair>teleport>teleport>fair on yoshi's story at certain percents). Combined with the fact that teleport is virtually impossible to edge guard, you can use it to make your edge camping game pretty much the best in Smash history because of the fact that at any point you can teleport onto the stage with no lag(and not only that but you have a chargeable projectile which you can charge while edge camping with very little risk). It's pretty ridiculous, honestly, and I can't grasp why no one does it.
I use this technique all the time, and because hitting the right angle to teleport onto a platform can be very difficult to do consistently I'd even say it will be one of the things that separates the great m2s from the average ones, but I've been hesitant to discuss it because I don't know whether it's intended and I'm a scumbag like that.
