Snake doesn't lose to Olimar. Stop trying to camp him =/
Diska, I think it's totally the other way round. There are hardly any good Snake players so people think Marth beats Snake [most people do].
Well, if I look at that question I kind of see a contradicting mentality in regards to the match-up. How do you expect to get in
if you camp? While Olimar needs a while to actually gain a % lead via camping you can't expect to straight-up outcamp him, can you? Grenades are there to block off pikmin or to blow up a couple of them at once. Use that and a mix of walking, crouching and jab1 to get rid of pikmin asap while closing the gap between you and your opponent.
Snake is one of the very few character who can challenge Olimar is his own comfort zone [full fsmash / grab range] - not even MK can do that to the same extent. Ftilt becomes your main tool once you're close enough to him to a point where jab1 to knock off pikmin isn't safe anymore. Just don't actually finish the whole ftilt string ... insteat you mix up ftilt 1 with grab [to dthrow] or another ftilt 1 until you see him trying to grab you - that's when you use ftilt2 to get him away from you. That's the range you always try to get him into from a neutral position. Note that you can also beat fsmash with ftilt 1 [some pikmin might survive that though but I haven't looked into it enough; I assume Havok knows though] and then immediately punish him with the 2nd ftilt.
That's what I believe the close-range game to boil down to: using ftilt 1 to keep him under pressure / kill pikmin up close and then interrupt his attempted counter / punish with a well reacted + ftilt 2. Finish the whole ftilt string should be done mainly if you know there's not enough time to mix in a grab or start another ftilt1.
Another thing that Snake can do that most other characters can't is circumventing Olimar's whistle-armor. Olimar can whistle almost all characters' aerials [including all of MK's aerials] - Snake's nair is the big exception because its hitbox lasts so incredibly long. Most people don't believe it but Snake's nair is a rather big issue for an airborne Olimar. He can whistle + airdodge it to the ground but that's a free grab or utilt [both **** Olimar horribly]. The way most Snake players approach this match-up it looks like a +1 for Olimar but I think toning town the camp game a bit [I know Havok made similar claim in the past and he supposedly never lost a set to Richbrown anymore after picking up Snake] can make this easily even. And I also believe that it will become necessary to deal more closely with the properties of each pikmin regardless of what character you play ... if you understand exactly how each of them works I can see this becoming a +1 for Snake.
Dude... who exactly are you, where are you from, and judging by your picture and the sign below it, you're a Mario main, right? So why are you in the Snake boards telling Snake players how their character's metagame is? Not trying to sound mean, but unless you have a lot of experience as a high or top level player of one of the characters you mentioned, idk man. Also players of different countries have different perceptions of the game and how it is optimally played - EU seems to fail at defense but has a strong offense, America has great defense and focuses more on that usually, etc.
Snake does lose to Olimar. Other than the very top level Snakes (Razer mostly), almost all Snakes lose to top Olimars. Heck even Razer lost a recent $50 MM to Dabuz (though it was close). I was at that tournament. I main Snake and second Olimar... I understand both well. I actually place decently offline in Texas, a very hard place to do well at. And I have played Dabuz too and other really good Olimars and watched plenty of sets of top players in this MU. I know what I'm talking about, more than most non-Snake/Oli mains would know.
That being said, the MU is arguable. But I'm dead certain that Snake loses it by a bit. Both rack up the damage really fast, but overall Snake dies much earlier than usual in the Snake-Oli mu (assuming the Olimar player knows how to use pikmin correctly). Olimar dies just a bit early, if and ONLY if you kill him with utilt or gimp him (Snake trying to gimp Olimar is a terrible idea usually, you may often get gimped for it if you're Snake). Olimar flat out outcamps Snake. If both players play really well, the Snake player is almost always forced to approach, though if Olimar messes up he can take a bit of damage. Olimar's mid-range game beats EVERYTHING Snake has. You over-rate ftilt1. It's rather slow, offline, and it's easily punished if Olimar is careful. His pivot grab WRECKS absolutely EVERY approach option that Snake has. Yes, if he spams grab and you PERFECTLY time it, you can hit him out of it due to his lack of grab armor. But getting that timing is hard, and for it to work Olimar has to be acting dumb. If the Olimar player is smart, you'll be shield grabbed for obvious ftilt attempts unless you have nades or something to cover you. Yes, it is possible for a Snake player to do what you say, but it's hard, and especially at low damages no Snake player in his right mind should approach Olimar under normal circumstances, seeing that a grab at 0% can lead into combos that take you from 0%-40/80% depending on how smart each of you is. If Snake is predictable without being super careful in almost anything on the ground at midrange, Olimar has the superior range to punish him.
Anyway I'm overall saying that Olimar is better than Snake at controlling the stage and at juggling, and Olimar's huge weakness in recovery is not as big of a deal vs Snake as opposed to most characters. Due to Snake's weight and bad landing, Olimar can build up the damage in an instant if Snake isn't super careful. You're right that when Snake is up in Olimar's face, Snake is in the advantage, but getting in is much harder than you think it is and you sound really dumb when you say that Snake can beat or go even at Olimar mid-range. He can't. Snake will almost always lose midrange. Also at high level tech chasing is hard and you can be punished for it if you're Snake.
No, camping is good in this MU for Snake. Unless there's an obvious good opportunity to get in (i.e. Olimar is in the air/offstage/under pressure by explosives/approaching without being super careful), Snake is best off a good deal away, chucking nades. At low damage, being close to Olimar leads to a lot of damage for Snake, and at high damage, being close is asking to die from an usmash/throw.
When you speak of Snake's aerials, you must remember that overall they are the laggiest in the whole game and ALL must be full-hopped to complete without major landing lag, though some require a second jump to have a non-laggy landing. 3 of Snake's aerials don't even have autocancels. You also have to remember nair is SDI'able. Olimar can get out under Snake and usnash/shield grab him for it.
The MU is -1. Playing defensive is not the wrong way to play it; it allows Snake players a chance to win, instead of going from 0-80 in 6 seconds and from dying at 120% from Olimar's usmash. Also, Snake cannot really cp Olimar stage-wise, as their strengths and weaknesses are very similar and they do well on the same stages usually.
Marth is also -1, there are few top level Snakes, but a lot more mid and high level Snakes than there are Marth players. Marth excels at punishing recovery and landing, and at pressuring his opponents to the ledge and then getting them offstage. If Marth stays on the ground all the time like a dumb 5 year old, yeah, Snake will lay on that damage in no time. But if both are smart and careful, Marth's superior range/juggling will usually lead to Snake in the air or offstage. Also, Marth is REALLY good at getting Snake offstage early. If this happens it's usually a free spike attempt, or about 70%. It's not even imo, especially considering that almost every cp stage helps Marth in the MU. Though on stages like FD it might be a bit in Snake's favor.
