How to counter assassins as corki?

Corki has great waveclear and harass. But it seems that almost any time im versus a Ahri, Fizz(sorta only if his jung gimps me), Zed especially, Akali is no prob, Talon not great unless again jung gimps me(it happens often since you squish), Ekko is somewhat manageable and now Zoe( wayyy too much dmg).

Please help Ive been doing great when jung goes bot or laner isnt assassin or weird off meta cheese.
