How do I win with Corki mid?

I know he's hyped up but I can't seem to win with him. He has OK waveclear but gets murdered by Malzahar in terms of both lane and waveclear. Many mids actually waveclear way bettter. He also has no CC so he depends entirely on his team to do meaningful damage. His poke is very cheap but does almost no damage compared to actual poke mids like Ziggs, Xerath, Lux etc.

I can bully some mids a little bit but they usually just shove me faster if I try and I can't clear the wave and harass well at the same time. His Q costs a lot of mana. I seriously don't see it. I'm 4-13 with him mid. Even when I get ahead, unless my team has a beefy frontline with CC, the other mid tends to be far more useful. Lux can land a binding on 2 people and nearly kill them both. I have some lame poke and decent DPS but that's all. How the hell is he even supposed to be good. Even in terms of the damage charts, Anivia, Malzahar, TF, etc. all seem to have a lot more damage by the end of the game due to their large AoE abilities. The only times I found Corki actually good were vs champs that lack all that like Fizz. However, give them a standard mid like Orianna and I just feel useless past 30 minutes in teamfights. One Malzahar E by itself takes my ADC to something like 25%. Despite being an ADC, he seems outclassed even in damage unless it's a long fight.
