Duress,
Gatekeeper of Malakir,
Smash to Smithereens,
Feast of Blood are some food for thought that I didnt see. I know running 4
Captivating Vampire is tempting, but with the Captain(which is better imo) and nighthawks, you have too many 3 drops. keep in mind Gatekeeper should also be considered a 3 drop as well. The Bump, Charm and
Terminate should be around but not in full playsets and not committed to the mainboard.
Duress, Gatekeeper, have non-conditional board presence 80% of the time. I recommend
Blood Artist or another 2 drop vampire for a more consistent threat.
