Okay, watching the Final Destination match.
Watch your spacing. It's good that you're trying to be a threat to put a hamper on his laser spam, but empty shorthopping when you're over two tipper lengths away isn't going to scare anyone. Maybe waveland into something when he jumps? Generally speaking, dash dancing is better than empty shorthops, anyway.
If you drop a chaingrab, react! Jab him for the tap reset or shield so you can shieldgrab him, or be prepared to follow him. Don't let him just getup attack you. Also, if you do get hit, don't double jump out of it unless you're going for a ledge sweetspot or you at least have an attack to cover yourself.
Good attempt to hit the Illusion with the jab, but if you wavedash back to avoid the ledgehop attack, hit him with something hard. Fsmash, ftilt, dtilt, whatever. Jab isn't going to send him off and is probably just going to work out against your favor.
Um. What? Shorthop Shield Breaker is not an approach.
Don't use more recovery options than you have to. At 0:46 you were totally okay without the Dancing Blade, so using it really just gives your opponent more time to set up an edgeguard. He didn't have the lightshield edgehog set up, so you should've just gone straight for the ledge with a Dolphin Slash.
Ledgehop? It's not hard to do, and it's usually your best option. Getting up normally, especially over a hundred, will get you screwed.
Jump cancel your grabs, dude.
I would consider using the dtilt against Illusions if you're consistently missing with the jab. Just a thought.
At 1:25 or so, you should've ledgehopped a uair when you saw him going over you to set up for a potential fsmash. Or at least nair or something. I think you messed up that edgeguard with the attempt to hit with the reverse Dolphin Slash. Don't. Just keep it simple. If you had gone straight back for the ledge, you could've ledgehopped a dair for the spike and the stock. Yes, it's cool to be flashy and fancy, but you don't want that to cost you the game.
I don't know why you were trying for the spike at 1:31. You're not going to send him off, and he's going to get to the ground faster than you, meaning he's going to punish you. Try for a uair to fsmash instead.
Your lack of ledgehops is really hurting you. Also, stop getting dash dance baited. Run INTO his dash dance if you're really trying to grab, because anyone who knows anything about dash dances is not going to get grabbed out of one.
You should learn the chaingrab. Looks like you don't really know it.
Why did you do that weird thing at 2:13? Just wavedash back and grab the edge. You wasted time with that... dash forward wavedash back, and you lost the edge. Not only that, but you almost got shinespiked.
Okay... the grabs at 2:22. I don't know why you were jabbing, you weren't going to hit him. Also, your opponent doesn't seem technically stupid enough to miss techs, and even if he did, you could react to his get up in ways much better than jabbing.
A getup attack? Over a hundred? Seriously, learn to ledgehop or I'm going to beat your children.
