When I first learned how smoke was going to play and how the kameos worked, my first choice was Darrius. Now that I know his setup costs full meter, I'm inclined to look elsewhere. I think Kung Lao, Sektor, and Frost will all lead to good oki too, and they provide more utility with cheaper/faster regenerating movesets. As soon as I can play tomorrow, I'm locking myself in the lab for a week looking for smoke oki.
