Bigman, people are counting CG's for Ice climbers.
This automatically constitutes Yoshi's CG and Grab release spike.
There is also edge-cancelled eggs, see theres a difference between doing it properly and doing it incorrectly, doing it incorrectly makes it easy for someone to hit you inbetween egg throws, doing it right makes it harder and grants you those nice premo invincibility frames =p.
Egg Toss is somewhat technical, while not grand in any sense of the word, like pit's arrows knowing how to shoot them properly is integral to yoshi's game.
Good yoshi's (not calling myself good, or even saying im doing this) can use Egg toss to bait, for defensive and offensive measures, however to do this you need to be able to control the egg to it's full extent, under pressure. Once you learn it, it becomes second nature.
Yoshi has a couple hard CG's too you know >.>
Edge cancelled eggs
egg lay foot stool
Draconic reverse
Draconic Trot(the qualities seem to differ enough that you wouldn't just use one if you could do both exactly...)
Chain Grabs
Grab Release spike
and this also applies to Lucas and Ness, DJAD, while quite novel, where you activate this can make a difference, it can mean you get to above the ledge and the invincibility frames run out just before you touch the ground, or that you go over the ledge entirely in AD frames, or simply that in the initial frames you were invulnerable so that you can use a move quickly near the peak of yoshi's height.
Not that technical but eh whatever.
Egg Toss.
I still think Link > IC's.
