I greatly disagree that their approach game is insane and they don't wait to punish things. The Koopalings actually stink at approaching in general, which is considered by Koopaling mains themselves as one of their greatest weaknesses.
This has basically been my experience when I've played against Jr. Dude seems to have a ton of trouble getting in vs Eggs. His zoning tools just don't compare to what Yoshi's capable of and Side B also doesn't seem to be a great a. He can put in some work when he gets in, but overall I approach the MU very similar to Kirby (ie, maximum campy lameness).
The only piece of ragemail I've actually gotten in this game was from a Jr player. He called me a "tryhard" and asked if I was just going to sit there throwing eggs all day, lol.
We need to talk about customs Rosalina.
We all thought she'd be weaker in a customs environment but she just gets immensely more powerful with Luma warp.
Wait what who thought she'd be weaker? I thought the consensus was always that she'd be one of the best characters, since she's already great with customs off and Speedy Star Bit and Luma Warp are so good.
Imo, Yoshi isn't terrible with customs, it's just that he's a lot better of without them. He gets a better recovery, but loses a fantastic projectile. He loses a command grab. He loses a kill move. 1111 Yoshi is the best set.
I've been saying this for ages. 1X11 Yoshi is definitely the best set overall (Side B is trivial). 1X31 has use, but only in specific matchups. I don't think Neutral B or Down B should ever be changed.
Is the shooting stars customs useful in any way for Yoshi? Also, Lick's okay, right?
Shooting Stars lets you abuse DownB more, but you lose a ton of kill power. Maybe vs characters who just juggle the bejeezus out of you so you can use it to get back to the stage, but no specific matchup is coming to mind right now.
You really can't drop Egg Lay because Yoshi's grab reward is too low. You need command grab to threaten shield. The free juggle attempt you get afterwards is nice too.
Ultimately Yoshi's default kit is just really well put together. Lick and Shooting Stars are not bad, it's just that they don't compliment Yoshi's other tools as well.
Rosalina's matchup with Diddy is so bad it's not worth using her in the matchup, customs or not. She potentially gains a few percent each stock with Shooting bits, and the occasional combo with Luma Warp, but it's not enough to pick her over a pocket counter you've practiced for half the time.
Eh, even in customs on I'm sceptical that Diddy has any matchups that are worse than even, it's not like you can really counterpick him. It's probably best to just stick with the character you know the best, don't underestimate the value of experience and familiarity. You're going up against impossible odds either way, you might as well have your best character on your side.
Anyway, time to go track down that customs tournament. Hopefully the twitch archive is still up.
