Honestly it depends. I'd say Havok or corvus and hyperion if he was awakened but Havok can get insane damage on his specials but once you ramp up corvus and get atleast 2 charges he's a Killer.
Definetely Corvus front the list, though Havok is a very good option, especially if you need defensive champs too. But based off of the picture, I'd go CAIW.

if he isn't a champ that you like to play with, though, then it's an hard choice between hype and venom, they are both really good ^_^
