It seems like everyone saw Armada camp Hbox and then assumed every matchup went like that. YL can't camp every top tier though.
Axe is an example of a player who knows how to play an aggressive Young Link very effectively and beat higher tiers like the Ice Climbers and Peach. Young Link doesn't have to camp to win but he at least has an option to do so. His N-air is very quick and his D-air is a good killing move. Also, I thought you can DI Zelda's throws so she can't follow up on them, but I could be wrong.
Yoshi is garbage. He loses to basic play from Top Tier and High Tier characters. Quite literally you can spam the basics with most upper tier characters and it beats Yoshi as a whole. That said he does have some very strong gimmicks. And yes I'm calling them gimmicks. Gimmicks aren't necessarily bad thing, a lot of characters rely on them. But Yoshi's gimmicks are extremely technically demanding and aren't beneficial enough to his character. Parrying is cool and all but the second you **** up you're now in shield as the only character who can't do anything out of shield. Also Sheiks existence as a whole really hurts Yoshi lol. Zelda and M2 are both pretty garbs characters but Zelda has one extremely powerful option as well as some very useable gimmicks(and just some legitimately good moves mixed in with some absolutely worthless ones) and M2 has one of the best movement games in smash. Powerful options tend to trump somewhat useful gimmicks.
I respect your opinion, but I disagree with your reasoning. I don't know where the idea that spamming basics can beat him came from since he clearly has the mobility and tools to deal with them. In fact, it's quite the opposite of what you're saying: players have to adjust to fighting Yoshi differently than most other characters since he is so unique. Shroomed, PewPewU and others I play with always tell me something along the lines of "Yoshi is so weird. ___ doesn't work on him like it does on other characters!"
I'll give an example to support my argument. When edgeguarding a character like Falcon, you don't really need to think about spacing an aerial to knock him back offstage. If you poorly space an aerial against Yoshi while he's recovering and it doesn't break his double jump, you're going to get punished for it and be counter edgeguarded in most cases. Fox is also unable to shinespike Yoshi when he's recovering at any percentage.
Parrying is extremely beneficial because it's probably the biggest game-changing defensive tactic in the game. Just when you think you hit him your attack gets countered and he has frame advantage because you're in hitlag while he's not. It's not foolproof of course, but it's still an option he has.
You mentioned that Zelda has one extremely powerful option, but Yoshi has multiple. His combo game with U-airs and extremely fast wavelands open up way more options for him that Zelda wishes she had. Yoshi's shield dropping is also the best in the game because he can't get shield stabbed, and he has an extremely good projectile that can be thrown in literally hundreds, if not thousands, of different ways. Zelda is also a much less mobile character.
The Sheik MU really isn't as bad as most people make it out to be because the biggest advantage Sheik has on Yoshi is chaingrabbing, which can be avoided most of the time if the Yoshi player is smart. This is a discussion for another time, though.
In any case, I wasn't disregarding your opinion in the slightest. Considering the lack of Yoshi players and the fact that they're generally not as skilled as mains for higher tiers (no offense intended), I can see how you think the character isn't too great.
