I present you the 
A beautiful void creature with the power to silence every assassin for the time required for a spaceship to reach Alpha Centauri. You may remember him from a previous meta where he was also played mid, and he still works just as fine!

Have fun in yolo Q!
shits on zed mid lane its not even funny. literally kick him out of lane. you want to harass from range zed? well I can just R->Q you every 20 seconds and chunk you out of lane. shield yourself when he ults. he will most likely not be able to kill you.
other than that you can pick non meta mid laners. basically any bruiser can shit on zed mid lane. i feel like ad champs would be better because of maw is pretty broken. but then again chogath the true damage ult. he will be stupid to ult you. as you can just nom nom him when he appears behind you during the death mark.
You can't kill what's already dead.
