I'm liking this setup of top tier and high tier speculation tier list...
Top Tier:
I really don't need to explain too much why Sheik is Top tier. I mean she can just throw out some aerials and they usually combo together. She has a guaranteed anything out of her throw, including bouncing fish from forward throw. Fair chaining into bouncing fish, good projectile that can also gimp, invincible and attacking recovery. She's good.
Yoshi though. Good aerials mobility allows him to approach and retreat within one aerial attack so good spacing. Up-tilt shenanigans into up-air. Downthrow to Up-tilts, up-airs, or an upsmash depending on DI. Good recovery. And her neutral B gimps very easily while on the edge.
Zero Suit is still good no surprises there. Down throw leads into anything. Up-smash, up-air, nair, or into an Up-B for the kill. Neutral B is a fantastic projectile. Up-air keeps opponents in the air. ZSS rarely even needs to go offstage. Her edgeguarding isn't the best, but onstage she's a monster. And she has a tether for recovery purposes.
Out of these 3, I don't think I have a definitive best character.
High Tier:
A:
Up-tilt shenanigans. Up-air juggles. And edgeguarding options with fair, bair, or Fludd. The only downside I see is his range.
Down throw to dash attack, into nair or up-air. Or down throw into Knee sometimes. Knee can be used less sparingly now due to the reduced lag thank god. And stomp now truely combos into knee. Falcon's recovery can be gimped, but besides that I don't see much faults.
Dude. Duuuude Shulk is good with 1 thing: Monado arts. Speed helps with grab and combo game, jump helps with edgeguards or killing off the top, and smash is...well smash. But the lag reduction helps him move so much quicker and he can abuse his monado range a lot better. Speed mode nair to f-smash is nice.
Oh yes Fox. Fantastic recovery, and the ability to fire off nairs like nobody's business. Up-tilt shenanigans into an up-air on occasion, and the return of the glorious Up-smash.
He's kinda like a ramped up Little Mac honestly. Incredible onstage combo potentials from Down throw, but man he can get gimped easily. Play smart against Diddy and you'll be alright.
B:
Overrated/Need more info Tier:
Maybe I just don't see the true potential of defensive characters in this mode.
Haven't seen enough stuff with him in this mode yet.
I really don't see Game and Watch potential.
Need more info as well. I don't see too much potential from these guys besides good recovery.
