It's been an hour, so this should be alright, I'm hoping.
Alright, here are my opinions on this MU. Forgive me if they're a bit wrong and feel free to contest them.
1. How does Dedede's ground game fare versus Snake?
2. How does Dedede's air game fare versus Snake?
3. Can Dedede gimp or disrupt Snake's recovery? How does Snake fare offstage versus Dedede?
4. Can Snake gimp Dedede? How does Dedede fare offstage versus Snake?
5. Is Snake easy to grab and/or chaingrab? Can we chaingrab him?
6. Can Dedede shield pressure Snake, and with what attacks can he do so with? Can Snake also shield pressure Dedede?
7. Can Dedede punish Snake's attacks easily on shield? And vice versa?
1. Snake camps us SOOOO hard! This is probably worse than Falco's laser camping, and if we ever get in close, Snake can just DACUS to escape and reset the situation. However, once we get in, we tack on HUGE amounts of damage. It's almost guaranteed, but explosives can hamper our CG's effectiveness. If we dthrow Snake while's holding or on top of a grenade, we blow ourselves up, too, and we also get interrupted if we try to CG over a land mine. The fact that the grenades explode if hit can be exploited. An f-tilt from D3, I believe, can set them off on top of him w/out risking damage to ourselves. Port priority actually makes quite a difference here. D3 will want to get the P4 port to make sure that if anything explodes near them while he's holding Snake, Snake will be the one sent flying. As I said earlier, we also have dthrow>dtilt (which can kill if dtilt is fresh and Snake is high in %'s) and good pummel release situations at the ledge. D3 can also utilize grab armor to avoid knockback from explosives, not only with his regular grabs, but with his Swallow as well.
2. As usual, our bair ***** most of what Snake has in the air. Probably the only two moves that Snake has to combat our bair is his own bair, which is laggy as heck, and his nair, also laggy as heck. Another thing that all smashers (not only D3's) should note is that Snake is easily juggled. His aerial mobility kind of sucks and once he's used up his DJ, he's free meat unless he ciphers away (which kinda makes him even more helpless). This is an important signal to utilize one of our strongest kill moves, utilt, more often. In addition, our super-disjointed uair beats out ANYTHING he can try from above. We are not even nearly in the same boat as him, cuz we have multiple jumps and a pretty good dair to boot. If we can bait out spotdodges, we can usmash and fair him. On top of that, our nair is pretty good at catching spot dodges.
3. Can D3 gimp or disrupt Snake's recovery? Well, can you read? Cuz if you can't, then that probably means you're not old enough to be fighting Snake anyway.
As I mentioned in my earlier post, our bair and fair knock him off his cipher. Bair, in particular, is a great gimping tool in general and should definitely be utilized to make Snake's offstage life as close to hell as possible. If Snake ever makes the mistake of ciphering close to the ledge, make sure you punish that with a grab release. You can follow up, and even if you don't, Snake has to hurt himself if he wants to save himself. Either way, it's a win-win situation. I'd say, offstage, this MU goes from a +1 to a +3.
4. It's hard for Snake to "gimp" D3 in the strictest sense of the word, but he can make it quite difficult for him to come back. D3's a pretty big target, so grenades and Nikita have an easier time hitting us than other chars. If Snake managed to stick you w/ a C4, then he always has that to threaten you with, and of course, there's always his good old usmash. According to Tech Chase's moveset guide, D3's nair can power through Snake's mortar but I'm not sure which part of the mortar he was talking about. He said that Dededes will find this info invaluable when recovering, so I'm guessing that he was referring to the explosive hitbox. However, even with all this, D3 shouldn't have too much of a problem making it back, not with all our jumps intact. If all else fails, Super Dedede Jump can muscle us back to the stage.....we can worry about the consequences afterwards (in this MU, the punishments for using that move can actually be quite severe).
5. Snake can be CG'd. Snake can be easily CG'd. We get more dthrows in a string of CGs off of Snake than we get off of most other chars. The problem is that it's not necessarily easy to grab Snake. He will be outcamping us. On top of that, we must not underestimate the range of Snake's tilts. I'm not even sure if his utilt can be shieldgrabbed at its max range.
6. Ftilt, as usual, is safe pressure. I don't really know if Dedede actually has moves other than ftilt, from medium range, and Waddle Toss, from far range, that can provide safe pressure on.....
anyone's shield. I'm starting to think jab can kind of provide decent shield pressure since the window of cancelling the second jab into the multi-hitting part is kind of large, so we can go for grab mixups. One big problem here is the startup time of the move, but an even bigger problem is this: why in the world would someone be shielding right in front of Dedede w/out a plan to get out of there? Dtilt, if spaced, is also sort of semi-safe. I think it has decent IASA frames, so we can use those. D3 reallly doesn't have much shield pressure to speak of, but honestly, D3's gonna be grabbing more often than pressuring anyway.
I'm pretty sure Snake can shield pressure anyone pretty hard. First, you have to consider the explosives. He can have 3 grenades, a land mine, a C4, and a Nikita/usmash/move of choice out all at the same time. Now, consider the ridiculous range and power of his jabs and tilts. Finally, consider the fact that Snake has a 1-2-3 jab, meaning that he can cancel any part of it, other than the 3rd hit, into anything else, like ftilt or a grab. All of this adds up to pretty decent pressure on Snake's part.
7. I belive D3 can shieldgrab most of Snake's attacks (provided Snake is in front of him and not behind, of course). Not too sure about utilt or fsmash, but I think everything else that's not an explosive is easily shield-grabbable, but that's why Snake will be hard-camping Dedede in the first place. I'm not very familiar w/ Snake's grab range, so I don't know what Snake can and can't shieldgrab, but I do know that D3 probably shouldn't be using moves that could be shieldgrabbed anyway.
