If you're still wondering why that CK isn't being picked - besides the obvious answer of trend shifting - just take a look at heroes that are popular now. Then consider how you usually deal with CK. You can AoE his illusions. You can jump him before he can ulti or BKB - heroes like Void or Sven could just BKB up and not give a fuck (assuming you didn't kill them), but if you take away CK's HP before he can ult his fight is pretty much over. Or you can just control or outmaneuver his ultimate like Lysah said.
KotL is a top pick and between Illuminate, Mana Leak and Blinding Light he pretty much shits on CK. Heroes like Batrider can initiate on him. Between those 2 and Magnus, Nyx, QoP, Gyro, Luna and Puck I would hesitate to pick CK, too.
