Caitlyn

her damage output can easily kill you. She's a major threat in the laning phase, with a good support by her side she will win lane.

Draven

As I've mentioned before with caitlyn about the damage output Draven is a huge threat because of his Q, therefore he will be a major threat since you wont have your Bork yet.

Blitzcrank

You have zero mobility in my opinion. The closest thing you'd have to an escape is your ult which wont do much but damage them, thus blitz is a major threat to you in the laning and out side of laning phase.
