Using COOOOOOBBBRRRAAAAAAAA! (sorry, couldn't help myself) as an alpha strike only is a pretty expensive alpha strike. While he is not very maneuverable, he can act as a flanker for you. If your opponents go after him first, light them up with the rest of your list. If they ignore him, position COOOOOOBBBRRRAAAAAA! in a way that constantly pits your opponent in choosing between two unfavorable moves.

I see this ship's role as control via threat. Don't want your opponent to go a certain direction? Place the snake there and dare them to joust or move away and be struck by the rest of your list.

This is how I view him, as well. I'm by no means a sports guy but think of TC as the clean up hitter in a baseball line up. You TLT'S are up in their face hammering away and ol' TC is lurking back waiting to pounce.

Perhaps when the JM5K drops he can pair with Dengar as a sort of scum version of Deci/whisper?

I see loaded up Xizor filling that spot. At least the SV has some good durability.
