P.S. I JUST started playing diddy
I can see that you have some of the at's in the works which is good, but I certainly noticed a good few things that are worth taking note of.
First of all, you got punished time and time and time and time again using the side-B to recover. Be careful about repeating that to often. On that stage specifically you could have jumped from below with a uair and then barreled onto the stage after relieving pressure. you could have waited until you were below the ledge to sideb and then barreled into the auto ledge grab. What i saw several times was that you would get even with the stage and throw the side b out, and he would just smash you back out. That, or you would get the ledge, then drop off>second jump> sideB and he would punish just the same. Marth is a great edgeguard, so you gotta mix it up more.
I also noticed that you were using the dash attack to get bananas ALL THE TIME. Just be more careful with that, because that's asking to get punished if your opponent starts reading it a bit. Just run up and press down+Z, or stop and hit A. Also recatching bananas off of shields and hits is FANTASTIC for applying shield pressure. Hit>recatch> hit > peanut > tilt, whatever the situation needs. But try to recatch bananas if you think you can without getting punished.
I noticed you also didn't use his bananas for much more other then straight horizontal throws. You can use it to edge guard by placing on on the edge and holding one, then when he goes to get up, you can zdrop over the ledge, or throw during his lag frames from the stand up or something. You can use them to control his spacing by throwing one up into the air, therefore making a straight line in the air that he would be taking a risk in trying to cross. Simply placing one someplace will limit him, so you can just use it to keep him on a certain area of the stage.
Finally, try to not rely on the nanas too much. They are a huge part of diddys game, i know, and they are quite essential to handling some match ups, but there were several times in this match, where you had an opportunity to juggle him, throw a few utilts, a uair, some dtilts or something to rack damage, and instead you would run straight to your nearest banana, and often times get punishing trying to do so. When I think about diddy, I see him in 2 zones. No nana game, and yes nana game. Because of the way he operates, you need to be good at both. So i would suggest spending some time practicing where you don't even pull nanas. It will force you to learn new ways around your opponents, making you more practical with his tilts, jab, grabs, aerials, and peanuts. Then when you add bananas, not only will you have a great utility for stage control, but you will be able to use diddy himself to his max potential.
Don't mean to rag on your diddy, I was simply pointing out some flaws so you can work on them. You were doing alright and you clearly understood the concepts of the glidetosses and his tilts. Just learn some more diversity.
