Maybe figure out a way to have multiple other characters activate.

Then, keep attacking for 5 damage with each activation for huge damage!

Not sure of a combo yet though.

He might work well with the new Human Torch thing about stunning guys with low Defense. And even without any combos, he's a guy with solid stats, range, and the ability to make 4 drops afraid to attack down at him.

There are just SOOOO many combos one can think of with this guy. Yes, you need to discard a card each time, but still. If he wins you a game on turn 3, it's worth it, right?
