Strengths

The egg toss is a good move for attacking from below an opponent. It is good for a board like Peach's Castle where you can go to the moving platform and keep throwing eggs at your opponent. This is also good because you can attack without actually having to move up to the higher platform.

The butt stomp is a great launcher that has high priority. It's great to use when you're above an opponent and you're both in the air. Also, in team battle, you can hit both of your opponents far away if they're tag-teaming on your partner. And, if someone is jumping at you while you're on the ground, use the forward butt stomp to counter. Also use the forward butt stomp when you are relatively close to an opponent and he has a Homerun Bat, Beam Sword, Ray Gun, or projectile that he looks like he is going to use on you. Since all those weapons work horizontally, a forward butt stomp counter should work wonders for you.

To get a few easy kills, stand by the edge of a board with your back to the ledge. If an opponent comes near you, turn your opponent into an egg and they'll fall off the board as an egg.

Turn your opponent into an egg to get a short break or to set up a combo. Or use it on one opponent in team battle and then quickly tag-team on your other opponent with your partner.

Has a huge second jump which allows good comeback on large boards (e.g. Sector Z), lets you get items on high ledges faster, and lets you avoid attacks more easily by jumping away from them.

Upwards head sweep is good at setting up a 2-hit combo and a great launcher (first 2-move combo).

Jumping head-butt is a good launcher which can hit an opponent close behind you, in front of you, or above you.
Yoshi's guard shield is very unique compared to the rest of the characters. Rather than being a shield that keeps getting smaller the more it is used or hit by enemy attacks, Yoshi hides in his shell. Therefore, even when Yoshi's guard shield gets weaker, it still guards his whole body and thus Yoshi cannot be attacked while blocking.
Yoshi also has another advantage to offset his disadvantage of his Up + B move when coming back. When Yoshi is in the air, he can take one hit without being knocked back by it. This can also be taken advantage of when using Yoshi's downward launcher, the forward headbutt roll. Just jump at an opponent who is coming back and press Right + A. Even if they hit you with an attack, it won't faze Yoshi and he should be able to get off the downward launcher for a kill.

Weaknesses

Has no Up+B comeback move. If Yoshi is hit far out and comes back, a good Up+B move from an opponent (e.g. Link's spinning sword attack) will send you out with no comeback left at all.

Trying to attack an opponent who is on the ground with the butt stomp from the air is problematic. In this situation, the butt stomp can easily be blocked and countered (throwing Yoshi after blocking it is usually the best option). Also, anytime you miss with the butt stomp, you're vulnerable to attack as it takes a second for you to recover from hitting the ground. If you hit a ledge in the air, someone can easily hit you with an upwards attack from below.

If you're above no ledge or ground and you do the butt stomp, a suicide is certain.

The forward head-butt has little range and can easily be blocked and countered. Also, Yoshi's throw is very slow and often, instead of sticking out his tongue for the throw, Yoshi will block--this makes his throw a move you should hardly use.
