Good mid laners against zed
I want to destroy him
I want to destroy him
No idea why this is downvoted? Just seems like salty Zed mains are coming out.
Not many I know of. He needs to be deleted from the game, in my opinion.

Just to name a few
does wonders against him. Also taking barrier helps tons.
Ahri is pretty good into him. Its a skill matchup tho so you need to be good with her. But if you are then its not bad.
Anivia mid, Lulu support and stick as a team. then it's gg for zed :)
Malzahar
anything that is safe and/or has invulnerability is great against him
Ziggs and lux are great safe picks against him (Zigss disengages with W, lux has Q and shield). You have to play like a puss and rush zhonias after a mana item, but both aare really good safe picks.
Now for champions with invulnerabilities or CC to lock him down you have malz, kayle, akali, fizz, azir, lissandra and ekko. This champions require to have more skill to play against Zed because of their ranges (the safest one is lissandra) and timing to dodge Zed abilities, but they are great
