So why DJC Nair out of shield instead of single SH Nair? Does it have anything to do with Yoshi's DJ armor?
Also, when is a good time to use eggs? Can I use them as a combo extender?
I generally like to SF Nair OoS for changing my spacing. You can waveland out of it and at least for my style, lets you dictate where and when neutral will start again.
eggs, as @
Mumbo
said, are good for harassing people's recoveries, dependent on MU of course, and are wonderful combo extenders/breakers/starters.
Every time I get an opponent off stage, I immediately throw an egg so it either kisses the ledge on the way past it or lands on the ledge. then I'll throw eggs to harass the opponent, but I almost never aim directly for them unless they're a fast faller or they have an iffy recovery when hit with an egg. Ususally I try to aim in front of them, not really to hit them, but to force them to take an extra second to think about how they want to recover. To 99% of players, eggs are to be avoided because they tack on percent, so they will avoid them at even a sub-conscience level, use that to space them out and limit their options. If they're at low percents, the egg to the ledge is good because it either forces them to guess where the egg is going to land and what option they can take. If it hits them and you're in position, it can serve them up for a downB. If the opponent is camping the ledge, eggs can make them more nervous than you being there trying to Fair them from ledge. If the opponent stays too long on the ledge, they almost always will be hit by the egg. When they go to drop DJ to get back to ledge, if they've stayed too long, they have no invincibility. Egg serves them up for downB or a Dsmash for kill.
On stage, eggs are a valuable tool to start and extend combos. If you're having trouble in neutral, toss an egg while retreating or approaching (on stage you always want to throw eggs while in the air so you're still mobile).
For approaching: Same as off stage, you almost never want to aim right at them, because they can just get out of the way or run at you. The first time, aim the egg so it lands just in front of them, maximum half their roll distance in front of them. If the opponent reacts with shield, you get pressure or a grab. If they react by rolling away, you can follow or you can toss another egg at them with the same kind of trajectory (land in front). Remember how they react to eggs and keep that in mind when you want to create pressure or approach with them. If they react with shield every time, it's safe to aim right at them and get a free grab or force a roll. If they react with movement, aim the egg to where they usually go, be it jumping dashing dancing whatever.
Adding into the idea of using eggs to approach and win neutral, the arc of the egg is important as well. If your opponent has trouble reading eggs or doesn't know how to react to them, throwing high arcing eggs, even randomly, can give you a mental edge. If you throw them high, you can get closer to your opponent to zoom the camera in so they can't see the egg or where it'll fall. This leads into another interesting idea with eggs. Throwing a high arc to the middle of the stage can seem meaningless, but what if you lose neutral there? what if you get grabbed right were it will land? The opponent gets egged, and all of a sudden, you have momentum and spacing for a dtilt or a grab. Against aggressive opponents, you can dictate where you're "vulnerable" and capitalize on the high arc egg that you tossed before hand. This is more of a trick than a reliable way to always win neutral, but it is a mixup and it is a way to hamper your opponent's momentum.
Last point I want to hit on is the idea of extending your combos with eggs. In this, the eggs are used in the same way as in neutral, it's up to you to capitalize on how the opponent reacts. Personally, when I knock an opponent any distance away that I can't immediately follow up, I toss an egg after them to cover a panic jump or a landing or a DIaway. Yoshi has every kind of arc you need to cover every character's fall speed and horizontal movement (not counting jiggs or floats). You can sometime place an egg so if they jump of continue DIing away, they'll get hit. My friends used to call them magnetic eggs because they appeared to follow you as you fell. Anyways, eggs are wonderful in the event that the opponent will land on a platform or land on stage in tumble. If you hit them, they are put into stun long enough for you (who should already be after them anyways) to get to them and get a free hit. If they tech in place to avoid the hit, you can get shield pressure or restart neutral, If they roll either way to avoid the egg, you get a free punish on them if you read the roll.
All of it plays into itself and followups are only limited on your reaction time and your imagination. If there're any points I missed, @
