I threw this build together last week and it's been pretty fun to play. The basic idea is to get in and do as much damage to your enemy by inflicting damage to yourself. Playing with such reckless abandon is pretty cathartic! Here's the list:

I believe the self-damage route with Quickdraw is a trap - his ability is better treated as a 'mini-Dengar' rather than something you should try to force, as otherwise you only accelerate his death.

I don't think Expose is ever worth taking outside of a Decimator (and probably not even then).

I think Pure Sabacc would fit your list better than Countdown.

Interesting list, sounds fun!! I personally tried QuickDraw, Sabacc, and whisper, so half of the list is suicide, and you have a phantom for the endgame.

Also forces difficult decisions, forces your enemy to choose between two 4 attack ships or the one that bites back...

You need to amend the name to Academy Award Winning Suicide Squad.
