pikachu is now one of snake's worser matchups...
falco is a stupidly insane matchup vs snake that it all varies on player by player
I don't see it, pika's CG is one of the easier ones to avoid IMO, snake outcamps and outspaces pikachu, out damages/KO's him aside from CG's and locks that only really hit you if you make a mistake...getting victimized by some ******** chain grab is nothing new for snake, I don't think that alone is enough, you need spacing/camping advantages on him that only a few characters like MK and Olimar have, and even then a lot of characters that have those advantages on snake are horribly outproduced for damage/KO power, destroyed by dthrow, or are themselves victimized by other tricks. pika may have a slight advantage on snake, but I can't put him in the same league as oli or MK...yet anyway, maybe I need a pika to kick my *** since he's so underused I guess
From my experience, Marth, Falco, and Pikachu all beat Snakeeeeeeee!
Snake beats Falco, avoiding his CG and camping isn't even hard you just duck and be stupidly patient. Then once you can't be CG > spiked you outdamage falco, outspace falco, and you shouldn't die until 180% OR HIGHER really. Snake/Marth is about even IMO, Marth WILL beat you if you DI badly, just like Wario, you need to DI everything upward well or else you will get set up to get spiked within like 5 seconds. DI up and cypher immediately, never get parallel or lower with the stage, even if you retreat for the blast zone you'd be surprised how far he can chase you off and kill you...If you avoid that then you have the standard "can't kill me until forever unless I do something dumb" advantage(marth can set up a lot of traps where you think you can punish him but can't and walk into a kill move, so knowing the character is part of it...). Marth can really hurt your landing options with fast falled uairs and pivot grabs, you need to mix up your landing well, I think I've found that nikita dropping is something I get better use of in this matchup than others, it prevents a lot of marth's option covering in this situation where he may have to just trade hits with you and not be allowed to continue the situation. I also find marth to be one of the harder characters to tech chase, not that easy to pressure him into doing something immediately. Definitely a hard matchup, I feel less comfortable with it than MK tbh, but I think that's mostly a personal thing....
edit: I agree that diddy is harder than falco, although half the battle is knowing what to do with banana's, it's why I think I should start playing diddy as one of my top 5 characters but I'm so lazy... <_<
