[2021] Low elo mid assassin counter.

Hey everyone, lately I've been playing some ranked and I've found that I really struggle against champions like Zed, Yasuo, Talon, Katarina and other similar assassins. Thing is, in low elo in my region they're all over the place, probably every 8/10 games on mid I'm up against one of them. So I'm wondering, are there any champions that can hard counter them? Preferably with room for skill expression and not too simple, but honestly anything will do. Thanks in advance.
