First let me say hold up on Marth. Once we do him I can almost guarantee that we'll have at least one Marth main on these boards getting angry at us. I want to save that hassle for when every other character is done.
@ Scala: I started having that feeling about Luigi a while back too, mainly because of his sick aerial priority. I didn't have too much trouble with his fsmash, at least not as much trouble as DK's. I do agree on the MK matchup, it seems ridiculous to me to think that 5:5 is an option at all.
@ Mmac: The problem is that MK is an aerial-based character. If he knows that you have a chain grab, he'll just jump high enough to avoid your tongue... as a multi-jumper, he can do that. Unlike Ike, he's not easily punished, and punishment is your main option in this match. I think it's leaning toward 7:3 a lot more than it is 5:5.
@ DanGR: It's just far too difficult to approach her. You can usually get an egg out before she gets a Din's, but after that initial bit you can bet she'll outcamp you. If she didn't have a reflector, it would be an entirely different story, but man, you just can't land a hit. If the opponent anticipates it, it's easy for them to hit you with an fsmash, and it isn't really a good option to approach from above in most matchups. Plus she outkills you and outprioritizes you. Trust me, it is possibly one of Yoshi's worst matchups, although Lucario is close.
@ Pikachu: Where to begin...
Firstly, I wouldn't say that this matchup is nearly as terrible as some of you are saying.
- Thundershocks are annoying but don't end up being that big of a hassle... all they do is shut down your ECE's, and that's only if you don't time them right.
- Thunder is obviously annoying, but Yoshi has enough horizontal speed that I've found it's not too difficult to airdodge past, or you could just double jump through it.
- Pikachu's dsmash is too good. Avoid the ground as much as possible, and stick to your tilts, grabs and jabs when you're in between aerials.
- When you're in the air, you win hands down. Pika's air game is very lackluster in both priority and range (yup, just like Melee Pika <3) and he doesn't really have the aerial speed to compensate anymore.
- Pikachu kills you fairly early. That's not as big of a problem as in most other matchups, since you can do the same, but it's something to be aware of.
- You can't edgeguard Pikachu. Ever. Don't bother trying, just chuck an egg or two and hope it screws up his flight plan.
- Fortunately, he can't really edgeguard you either. His usual annoyances (fair, thundershock) don't really hold a candle to what Yoshi can do back. Something fun to try here if he tries to intercept you aerially is to egg lay him. Not really necessary, but it pisses off your opponent and gets him off your back.
- If he stays on the edge, get ready for thunder or dsmash spam. Just get off the ledge in that case, usually with a nair ledge attack. Make sure you time it so that your super armor absorbs the first hit of his dsmash, otherwise you're trapped.
- QAC isn't a horrendous problem. If you think he's going to do it (and there's a reasonable amount of lag time beforehand), use usmash to cover all your bases.
So it's not an easy matchup but it certainly isn't TOO hard. 4:6?
- Pikachu can't be edgeguarded at all.
