Why don't more people play AP Shaco top?

Just played vs an AP Shaco top. It's is literally an unwinnable lane. There is absolutely nothing you can do vs him in lane. I'd even go so far as to say, it's unfair. I'm curious, why isn't it played more. I can't see any good Shaco player ever losing lane playing him AP top. I see no reason why any Shaco main in Silver or even Bronze can't get Diamond with this incredibly strong pick. You just auto win lane every game. I'd do it myself if I didn't find Shaco unenjoyable to play.
