Meh I hate to be a dousche but I don't think everybody needs their own video thread. I considered myself a fairly well established diddy main and I just put my stuff in the critique/video thread. It's not just you, I dunno I just get annoyed when half the threads on the board are hay look at my diddeh threads.
That being said I will watch these later today :D
edit: critique!
cons: you recover poorly, and you really can't afford to do that against marth. It is hard enough to recover vs marth, even if you mix it up well.
^same goes for your ledge game, I admit this is extremely difficult.
I didn't really see any peanuts and the only time i saw dribbling was when it wouldn't have helped anyway.
Uthrow is your best friend in this matchup. You really need to use it, it makes the marth matchup so much easier.
I recognize that those were friendlies, but blindly approaching marth is dangerous a lot of the time.
Be careful about taking him without a banana, if he is inside your defenses and you are bananaless marth may be the hardest opponent to get back out of your defenses
pros:
i liked your use of nair, you used it to combo at smart times.
you dsmashed him once when his recovery didn't quite get the ledge. Imma steal that.
the time you plucked a banana then diddy humped him was a great mixup
you were playing marth on his best stage the whole time and did fine; playing marth on battlefield can make anybody look bad.
you were pretty smart about when to zdrop and when to instant throw
the time you got him to di one way then threw him the other way was really smart.
one last thing: make marth prove he will up b you out of your usmash before you cease using it, usmash is pretty useful in this matchup when marth isn't annoying you with that.
nice diddy! hope this helps some!
