Yoshi ranks 6th in the C tier on the current tier list, in the very middle position. Yoshi is known for having unique properties compared to the other characters in the game - his shield, an egg rather than the standard energy bubble, doesn't shrink (making him completely immune to shield stabbing), allows parry techniques, and lasts slightly longer than the normal shield. In addition, his midair jump gives him a type of launch resistance throughout its duration, allowing him to escape combos and even hit back. Yoshi's stats are rather unique as well; despite him having above average weight, he has decent dashing speed and the fastest air speed in the game. Yoshi's down aerial is known as an extremely effective damage racking move, dealing a maximum of 56% damage, while landing the move is made even easier using the DJC technique that can also be applied to his other useful aerials. His forward aerial is an effective meteor smash with very quick startup yet high power, along with the ability to combo into it with moves such as forward tilt. Yoshi has useful combo options outside this, including a versatile up tilt that can juggle fastfallers or heavyweights at low percentages, and lead into an aerial or up smash, with a late-hitting neutral aerial being able to followup with another up tilt to continue the string. However, Yoshi's above average weight and size make him rather easy for quicker characters (such as Pikachu and Fox) to combo. In addition, his grab is possibly the worst in the game due to being very slow and punishable, yet having limited range compared to other tether grabs. Yoshi also lacks a rising up special move to use for recovery, forcing him to use his double jump, meaning that if he's flinched out of his double jump, he will be unable to recover. Yoshi's biggest problems, however, are his huge difficulties dealing with pressure, especially shield pressure, as well as lacking reliable approach options with considerable range, making it very easy for characters with disjointed moves (most particularly Kirby's up tilt) to simply outspace him constantly. While Yoshi does have a projectile in his Egg Throw, it is too slow and difficult to control to be effective, while he also lacks a reliable way to deal with projectiles. Yoshi's properties give him very average matchups, with his matchup spread having an average of 50:50. This means he generally has trouble against higher tiered characters, but can do well against lower tiered characters, though he has a handful of even matchups against characters near or below him on the tier list.
Yoshi is a surprisingly heavy character (third heaviest character in Smash 64), yet is relatively quick, with the fastest air speed in the game, plus a moderately fast dashing speed and fast walking speed to compliment this. He has an average falling speed and fast falling speed. Unlike other characters, Yoshi's shield is not an energy bubble, but a Yoshi egg, which lasts slightly longer than other shields and is also immune to shield stabbing due to covering his whole body and not shrinking (rather, it becomes darker to indicate how close it is to breaking). However, it takes slightly longer to get out of than other shields, plus Yoshi has a rather sluggish roll, limiting his OoS options (though he can jump out of his shield, unlike in Melee and Brawl). Yoshi lacks a third jump, but his double jump is very large and also gives him a special type of launch resistance during most of the animation. The unique properties of his double jump allow him to "double jump cancel counter", which enables him to escape combos and counterattack.
Yoshi doesn't have many KO moves, though he has some fairly powerful moves, such as his forward smash and forward aerial (the latter of which can meteor smash). He has some effective combo moves, such as his forward tilt and up tilt. The former has high hitstun and can easily combo into a forward aerial at mid percentages. The latter hits opponents vertically with set knockback, allowing it to easily lead into aerials such as back aerial and up aerial. This is also an effective KO setup at higher percentages. His up tilt can also juggle fastfallers at low percentages, which can also be done in conjunction with an up aerial. Yoshi's down tilt also has set knockback, and sends opponents on a semi-spike trajectory, making it a useful edgeguarding move. Yoshi can use a well-known glitch-tactic called double jump cancel, allowing him to use aerials quicker and combo with aerials more reliably. It's especially effective with his down aerial, which can rack up a huge amount of damage (maximum of 56%) somewhat quickly. Yoshi can parry by using his shield at a perfect moment (within 4 frames of being hit) and can then hit the opponent immediately. In high level play, Yoshi is known for being able to break shields quickly using his Z-cancelled neutral aerial while using DJC. This is known as a shield break combo. His DJC'd down aerial can also break a shield if used correctly.
Yoshi also has a projectile in his up special move, Egg Throw. It is difficult to control, however, due to the arc that it travels in, and it is too slow and short-ranged to be as effective as some of the other projectiles in the game. The explosion does have good range and power, though.
Yoshi has a number of weaknesses, however. He has a lot of trouble dealing with pressure, especially from characters tiered higher than him. While his recovery can travel a decent distance due to his very high air speed, getting hit out of his double jump basically leaves him helpless, as he lacks a third jump to use. Even weak projectiles such as Fox's Blaster can cause Yoshi to lose his third jump. Yoshi's grab is possibly the worst in the game due to being slow and laggy, as well as lacking range compared to other ranged grabs (Link and Samus's grabs). Yoshi is also fairly vulnerable to some combos due to his above average size and weight. In addition to this, his reliable approach options lack range, giving him large trouble dealing with moves like Kirby's up tilt and Ness's down smash while approaching.
Yoshi has very average matchups overall. Against characters tiered higher than him, he is heavily countered by Pikachu and Kirby, and also has trouble against Captain Falcon and Fox. Overall, Yoshi does well against the lower tiers and poorly against the higher tiers, granting him a spot around the very middle of the tier list. What sets Yoshi apart is that his unique characteristics and the overall lack of high level Yoshi players makes him a unique matchup for any character.
Spins 450 degrees while saying "Yoshi!", facing its left after the 450 degree twirl. He then does the following twice: raises his heels off the ground, raises his arms and opens his mouth, and says "Yoshi!" once while spinning.

 Notable players
 Double jump cancel
DJCing is a glitch-technique that can be used by Yoshi and Ness. It involves using an aerial just after starting a double jump. This cancels the momentum of the double jump and allows quicker aerials, while also being able to speed up short hops, making short hopped DJC'd aerials especially effective when Z-cancelled. It can also help with aerial combos.
 Shield counter
By shielding at the precise frame a move hits, Yoshi can drop his shield immediately and attack out of it.
 Double jump cancel counter
The unique properties of Yoshi's double jump allow him to use the launch resistance to avoid an opponent's attack, while using an aerial with fast startup (preferably a neutral aerial) to counterattack.
 From the Game
Yoshi is the friendly dinosaur of Yoshi's Island. He began as Mario's partner, but has since built his own identity, and now appears in many games. He uses his unique ability to turn whatever he swallows into an egg as his foremost attack. Yoshis come in a rainbow cloud of colors and are said to have a high IQ from a very early age.

Yoshi is the cute dinosaur who lives on a tropical island. You'd be surprised what he can do with a simple egg.
