@ 6 minutes
hope this helped u guys a little.
Those counters killed you vs Shin :/ Try walking more in neutral, way less committing then empty hops (if your opponent dashes to shield like shin was doing you can just dash grab/roll away behind vs being in the air and trying to aerial a shield or change your landing position because you're in an awkward spot) More dtilt traps would help too, and more dtilt in general. As Marth learning to stuff approaches will help you go along way because stuff approach-->gain stage control-->ledgetrap/edgeguard, where Marth is most potent. Learn to read dash to shields and make people fear using them against you, which forces them to approach different ways and opens the door to you get more/better punishes.
When ledgetrapping, just dtilt unless you've got a hard read on what they're going to do. This isn't the brawl days where a drifted back nair single-handidly destroyed people's attempt to get back on stage, doing an aerial on shield is likely to get you punished if not put you in a bad state. Dtilt's so much safer and faster, and allows you to react to what they like to do to it.
You had great follow ups, especially after knocking him down to the ground and he didn't tech. if you read that you can stutter step forward f-smash instead of dash attack.
When you can, watch the match again and see how many times he dash to shielded, trust me, you'll be surprised. Learn to recognize and grab him!!
Geez the amount of dash to shield-grabs he attempted sickens me. Reminds me of 99% of the Luigi's I fight. He literally tried to dash grab you with a banana by your feet.
P.S. I like how you started of BOTH games with an instant dash grab...then like forget how to the rest of the matches hahaha, I'm telling you learn to read those and it'll help so much. You can even get guaranteed shield breaks using sb since people are stuck in that dash animation if they try to shield. If you sense a dash to shield coming and you're spaced right, they'll be forced to take the hit and if their shield is low--POP!
