Out of those three choices Kennen. Because he run on energy, has damage/escape/CC in his kit, and still has his ult for team fight when he's behind. Protobelt, Abyssal, and zhyona's are great on him and they give him 30% cooldowns.

HE CAN SUPPORT TOO

These can all flex between the two with good results if the time is taken to learn them and their match-ups properly.

I GO EVERYWHERE imho kennen is the strongest of those three.

Cho'Gath, Kennen, Jayce are you best options.

He can actually be good mid if you learn him
