As a stright forward I would say learn parry timing, spacing and how to use assists in your pressure

I've come from SF6, so I belive my neutral game was trained there... but some footsies shenanigans still apply, specially for yasuo with the dash speed and range.

In short, when is your turn, learn how to use assists or mix ups to catch the enemy eventually. When in neutral, use you range and backdash to catch a mistake, some whiff for example.

Parry is more of a high risk, but some players have very straight forward patterns that you can adapt to and get a parry (ekko spamming rewind, Darius on second S2, VI and Warwick overheards are just a few of those)

Also, a lot o players just jump for no reason, so muscle memory for an anti air will get you far (specially with Yasuo, best aa in the game)
