Heard discussion of recoveries, thought I could suggest some changes.
Mario- perhaps let him walljump at the top of it, by having it put him in special fall akin to sonic (so he can attack while falling) in that manner it would boost his on stage game too, as up-B OOS is a great option for mario except it was so horrible because he had to fall in helplessness to the stage, this would give him a great on stage option, and a better recovery.
DK- give him the melee hit on startup again, and otherwise he is pretty good.
Link- w/ AGT and bomb jumping back, I'm sure he is fine.
Samus- her recovery is already good, AGT zair will only help it.
Kirby- Give the startup and end frames of rock (down-B) heavy armor.
Fox- already pretty good.
Pikachu- already great.
Marth- he is already good.
G&W- good already, you could bring back melee version or keep brawl, both are good.
Luigi- w/ jump to down-B, side-B, and up-B all as good tools for recovery, he has a linear recovery, but that isn't necessarily a bad thing. Buff side-B a tad bit?
Diddy- he already has a good recovery.
Zelda- Allow jump cancelling naryu, cut a few frames off up-B startup.
Sheik- already has a great recovery, maybe make it so you can grab the ledge out of up-B start, like in melee?
Pit- he has a good recovery, but it is a bit slow to fit in a melee environment. I suggest further discussion on what to do with it.
Meta- he has a great recovery, personally I suggest buffing dimensional cape so it starts and ends faster and doesn't put you in free fall, increasing the movement speed of side-B, making him a fast faller so he flubs in the air, and giving him low priority. Turn tornado into something like marios melee down-B, where he can't fly around using it, and instead it stays in place and multihits for a second, and then ends.
Falco- Increase the length of his firebird.
Squirtle- Make it so if you hold B, it has a strong hit at the end of it, but if you don't he doesn't go into freefall and can attack out of it.
Zard- He has a pretty good recovery.
Ivy- In need of radical redesign, I suggest discussion.
Ike- Jump cancel his aerial side-b as well.
Snake- If he still has a jump he can jump out of it to cancel.
Peach- Make it so side-B can hit the wall and bounce up and off.
Yoshi- he already has a good recovery.
Ganon- Make the grab box on his up-B bigger, and when he lands it there should be enough hitstun that they can't automatically punish.
ICs- already good recovery.
D3- make him flub a bit less in the air.
Wolf- looks good.
Lucario- make his up-B airdodge cancellable, which would improve his onstage game as well.
Ness- buff his zap jump and give him heavy armor while controlling pk thunder.
Sonic- decrease the height gained, speed up his ascension.
Bowser- already good.
Wario- make his up-B controllable while he rises, so he can weave like his normal playstyle.
Toon Link- already good, AGT will help alot.
R.O.B- needs discussion.
Olimar- needs discussion.
The captain- already good.
Jiggly- his recovery is already good enough.
Lucas- Zap jump is already good enough, along with the other facets of his recovery.
Pit, R.O.B., MK, Olimar, Ivy. They need serious work on editing their recoveries.
