Captain Cranium is an interesting card, indeed, though it's one that I often overlook. Did you know he's named after a Hiver? Deck building with that card should be interesting to say the least. I'm not sure how I feel about him turning my crew into only criminals. Maybe his other traits make it worth it but, at a glance, I'm not too fond of him. Haven't really theory crafted with that card in a deck yet.

I think it's really interesting where the game might go. He does but you on the ground floor of the criminal syndicate thing... if that has any appeal.
