Something else to note: Nair can combo break sheik's ftilts
Not if you are playing a decent Sheik that can space the combo properly.
FAir both outranges and denies Yoshi's NAir.
I tried it for a long time too, since there are a many Sheik mains over here. But dropped it during my last tourney since it didn't work anymore after the pool matches.
Sheik's FAir and her Bouncing Tunar (Down B i guess, that flippedy flop thingey...) are pretty much her strongest moves which you have to be aware of while facing her.
If she tries to FAir string you, vector away from her and interrupt it (if needed, DJ).
If you want to interrupt her string by being more aggressive, DJ into her FAir while getting ***** and NAir her after sucking up her FAir with the superarmor.
I wouldn't try to fight her FAir strings by brawling in melee range.
Try to kite and punish her with Egg Tosses and Egg Lays.
I wouldn't recommend to fight her Bouncing Fish engages either.
Its hitbox is ridunkulous big and hits hard. Also her hurtbox is ****in' weird while bouncing around, which makes her almost untargetable.
Try to punish her landing lag, if you can read the move. Also, better not try to pivot grab it, cause you will miss, and the fishy fish will rek you.
Try to keep being airborne, as her only ranged poke tool are her needles.
Don't try to pressure her shield with moves that make you land next to her. All of her moves have very little startups thus making you pay for your engage.
Don't ever try to gimp her, just throw eggs.
Her Up B is ridiculously good in this game. It both makes her hurtbox friggn' weird (again), and its first knockback is a very good kill move.
The combination of dodging almost all of Yoshi's attacks and killing/stealing his DJ, makes this move too strong.
These are just my 2 cents and the experience i got so far.
You may now proceed.
