THE CRITIQUE
Okay to start off the opening 0:09- 0:16, there are a couple things you should keep in mind at the neutral.
1. You can crouch cancel all of his moves(Besides tipper Forward smash and Dair)
2. Pull and utilize turnips ALOT. If you have space(to pull), there should always be a turnip in your hand.
3. If he knows the you can CC his moves, he will be going for Grabs, tipper dairs, and tipper Forward smashes (under 40% that is). Since you know this, only space out of those moves. You shouldn't be worried about his long dash attack if you can CC it.
Okay so you started off trying to dash attack at his dash dance. Personally, I wouldn't try to go for this for a couple of reasons.
1. He can CC it (0%)
2. He can dash out of range
3. It's a grounded Marth
Vs Marth, I would use dash attacks only for tech chases and when Marth is airborne. Marth 101 is basically throw turnips. If he shields, grab. If he jumps, dash attack.
Also at 0:15, he fthrow> Tippers you. I honestly have no idea what kinda of DI your supposed to have for that LOL, but I'm pretty sure its down and away (someone confirm that)
0:26, I don't know how I feel about Fthrow>Fthrow. Like, I understand that it worked and all, but I also wonder if you can get a follow up after an Upthrow. (Someone confirm that)
0:30, both of those aerials on your shield were not safe by Shady. You could have naired out of that. Always try to remember that when your in shield vs marth, for misspaced aerials and grabs. The first misspaced one I'm okay with you not getting it, but full hops are 95% of the time unsafe in that position, easy to nair OOS with that.
1:26-2:06(The period of time you were at high percent vs his fresh stock) I REALLY enjoy how you played that. Very solid dude. I also recommend adding a tool that I try to incorporate, that being run up Shield as well as WD back oos. What this does is kind of force your opponent to misspace a move if you shield in there approach. This can help you get a grab , Nair OOs, etc. What you use the WD back OOS is for grabs. If you think he is trying to grab you after he realized you want to shield, you can WD back to make him whiff the grab into a dsmash, grab, jab, dtilt etc. Other than adding that you played that well, mixups of offense and defense as well as using your turnips wise and frequent.
2:09 I don't agree with you using FC aerials to come into Marth in that situation. In my opinion, I would use that only:
1. Retreating or in place, to keep your space. (as well as harder to punish)
2. When my opponent is cornered to a point where he cannot Dashdance
3. After using a turnip
I have been doing alot of thinking, and someone can prove me wrong with this, but approaching with FC Fair and taking up that much space isn't the best idea. If you will do it, do it little by little. Don't try to claim big chunks.
2:16 DO NOT EAT THAT PERCENT. That is something that is easy to avoid.(Though you DIed it perfect LOL ) Marth was in the air and you were on the ground. In this situation, think of it like this; what can Marth really come down with?
Aerials, Shield breaker? Can't land and grab, you can react to it before it happens.
You were also at 0%, so you could have done 2 things.
1. Shield, wait for what he does. If he aerials, wait, nair oos. If not, just nair oos and hit him LOL.
2. CC his aerial(which ever he chooses) and punish with dsmash, dash attack, grab , nair, etc.
2:20: A moment of fear. The dsmash was bad because he wasn't in range. Like, he rolled, then you dsmashed. NOt the other way around. Also, the spot dodging stuff, you could have had better ways out. It looks like you had a little bit of room to WD back and set up for another move (It looked like you understood he was going for the grab, so you can try to WD back and try to beat it out with a dash attack if you were confident about him grabbing. If not, you still had more room. At the edge, he would have to run up grab to get you, which you can react to) OR instead of WD back, you could have jump and floated for a bit, see what he does, try to get him with a fair. Or you could have floated off, but I think that is giving up too much space personally. Try out these escape routes!
3:02: You just shielded too close, you coulda got a nair out of his jump :3
3:45: With the air dodges, something you can try to do is air dodge closer to the stage. This give your opponent less time to react to the airdodge, and you can move freely sooner.
You played alright the rest of the match, but I just realized I critiqued the match that you won. But there were still some flaws. If you have any questions, ask away :D Also, if you want me to critique another match I will , it's just it late now and I'm tired lol.
