RedHalberd, forgive me if this next post sounds biased, but Marths play the Diddy MU so wrong. I constantly tell all Marth players exactly what to do against Diddy. However, they do not listen. I FREQUENTLY find myself correcting mis-advice from Marth players to other Marth players.
I have lost to three different Diddy Kong players in tournament. In 2008 I lost to Deez. I have defeated him at least twice since that first loss in either tourney or MMs, and have not lost since. Since this will eventually be posted publicly, I will fairly note that I declined his challenge at Pound 4 (the most recent challenge), because I hadn't been practicing the Diddy MU before that.
I have lost to Alphazealot in tournament at Pound 4. However, I do not hesitate in the slightest in saying that my performance vs. him was subpar, and I didn't utilize ANY of the normal strategies I would normally employ in that MU. AZ already knows how much I respect him as both a player and a person, but I will still make it clear that I'm not saying this to make johns, because I was outplayed regardless. I'm just noting because we're discussing MUs and MU theory. I'm 1-2 in sets with ADHD, and slightly under-even with him in friendlies, which we play a lot of.
(A private note to AZ, if you'd like to play me at my best, we can do so at Raleigh, but I'll need a T.V. with no lag
.)
I'm going to watch some videos of Neo vs. ADHD, of Ally's Marth vs. ADHD. MikeHaze vs. any Diddy I can find, etc. However, I confidently feel that when I'm playing correctly, I'm the best Marth at this MU by a significant margin SHEERLY off the fact that I use the most effective OVERALL strategy vs. Diddy in the MU.
Trap Diddy on the ledge, keep him there. The end. If you don't know HOW to do this (you'd be surprised, but people really DON'T know how do this) then you don't know the MU. Learn to crouch to reduce getting Faired. Learn how to take control of bananas, and repel banana attacks without leaving yourself open. Learn how to pressure Diddy, and utilize your sword properly, even with bananas about.
My fellow crewmate R00kie somewhat recently dropped Fox for Diddy. ADHD and I have been teaching him the character. He's extremely talented, and knows how to fight Marth very well, as we play a lot (he's also trained quite a bit with Neo, before anyone wants to jump on the, "But maybe he just knows your style" bandwagon). I've taught him the effective strategies to use against Marth, and use my strategies against him and other Diddys, so I'm reassured that the MU is being played correctly from both sides.
I know this MU at almost every angle, and therefore I'm confident when claiming that Marth has a slight advantage vs. Diddy when he plays the MU well, both onstage (the hard part) and the securing the traps, and maintaining good defense. I can also claim that I know the character Diddy pretty well, as I've beaten Diddy players including ADHD with other characters as well including Falco, Mario, and MK, and personally developed several of that character's modern strategies.
Also, Marth players MUST have good item control. Even though we should not attempt to utilize the items too much, item control is still a resource that many players lack.
I'm particularly skilled at the MU, but I don't dominate Diddy players like ADHD or R00kie, because it's not **** for Marth. It's probably 6-4, but I'd believe someone saying it's 55-45 Marth. I don't feel it's even, I feel a distinct advantage going into that MU, unlike R.O.B. or Donkey Kong. I simply know the best options of both characters, and I feel that as the match pans out, if both players are doing what they should be doing, Marth has a solid advantage.
