Okay, so you do mash out perfectly and stop mashing before they stop pummeling, then good job you saved yourself about 5-6% of damage, but if you don't, you're dead, and it was all for nothing. Be smart about what you're doing, too many people theory craft and that's fine, but theory crafting is in a perfect situation, and a lot of times it doesn't come through for you in your time of need, but in theory it should.
I’m not theory crafting here. I’m just saying that while Fox’s grab release > up smash is no where near guarantee’d, it happens often enough to be recognized as a practical setup.
It’s just a setup that you can bait. I’m trying to prevent ridiculous theorycraft like “Fox will never ever ever ever ever ever ever ever air release > up smash MK because no MK will ever attempt to mash out” because that’s simply wrong. It happens against even good MKs.
Weigh the good and the bad here for a second, and realize the bad heavily outweighs the good. It's a simple decision after that point. I stick by what I said, no MK should be getting air released to Fox's Upsmash.
While maybe it shouldn’t happen, in the real world where we aren’t theorycrafting to a ridiculous degree, it DOES happen.
I don’t care if theoretically it should never hit you. In practical play between two humans it’s happened often enough to high-level players who know the mechanics.
Whether or not MKs SHOULD get hit by it is irrelevant when MKs, even really good ones, get hit by it. There are a lot of things that if we’re playing technically perfect and not making big mistakes that would never happen, but they DO; because we’re human.
It’s not guaranteed but it happens enough in practical play, I’d say, for it to be considered a valid kill mixup.
@Kragnor: Dimensional Cape can actually be a really situationally good recovery. It's great in the ditto because if you do it at the right angle and wait until the right time (which you can do by sitting in the air and up airing), it's really safe.
And sometimes as a bait, too. A lot of people don't know about auto cancelling the DC (without the attack) from a platform so that there's no lag, so as a possible mixup you
can try auto cancelling a DC off a platform, and since there's no lag, shield or spotdodge or whatever when they try and punish you, and punish them in return.
I wouldn't do it more than like once, though, lol. It's kinda like throwing in a doop walk into your approach. If you're playing someone good, they usually won't fall for it more than once.
