plz help me! i know i messed up after the first stock head jump thing. just tell me what i'm doing wrong plz ):
The Diddy MU... that's a pretty harsh one it is. Diddy has not just the speed, but the projectiles to gimp/set you up into attacks of his own. Based on what I saw, I'll give what advice I can:
- The times you went for the full DB you'll need to make sure that every hit chains properly, as every additional swing adds more commitment on your part. Otherwise, it results in repeated punishment, as that Diddy demonstraited. What you can also do is purposefully stop midway (like with the DB setup) to make them react a certain way like air dodge then punish them.
- Two times you went for a hard read FSmash, but those are extremely risky as you know. Not that it is necessarily wrong the way you tried to read them, but just note that there are safer options to rack up the damage/get the kill. You'll need to weigh the risks, especially against a character that has two of Marth's weakpoints in his favor.
- Though I am unsure of which direction exactly, but there is a way to DI out of that setup Diddy kept going for. It seemed unlikely that he would go for anything else, so hopefully someone with better Diddy MU knowledge can tell you how to escape it. My best advice would be to shift between DI'ing left and right so the Diddy will have to guess on where to jump. You just need a moment to get that air dodge roll out and you'll be mostly fine.
- I'm sure you noticed how the Diddy did a few light hits in the air with the bananna or otherwise to get you into another attack like a grab. This tactic is based on your hesitation, and it can be escaped by double jumping. You could either use that momentum to go for a retreating FAir, cancel your air momentum with DB1 then followup (Air DB setup in other words xD), or SB yourself away. You also have similar tactics yourself, though its a choice if it fits your playstyle or not (My guide has that all there for ya on setups/combos section if you wish to read it).
+ To end on a better note, your item control was really good (I'mma need to take notes from you there xD), and you knew the method to get in.
You're on the right track to beating that MU though, so keep that practice up.
I'll watch it a few more times then edit in any more info I could give ya on the matches. But for now, I hope this will help ya out ^^
EDIT:
+ Those out of shield options are going to be your main points for keeping the spacing solid, and I saw you went for them at times which is great already. Marth when faced with an opponent faster than him will more likely be forced to play defensively, so mixing up between jump cancels +FAir/DS, grabs, or simply putting the shield down and going for a tilt (probably DTilt is your safest bet), so you can force your opponent to slow down on their agro. You already were playing it a bit, but I get the strangest feeling you'd agro if you had the chance - problem is Diddy makes that hard for any Marth to do.
