Put this together for FNM's.  They didn't have Psychic Spiral, Elixir of Immortality, Sign in Blood, or 4 Vampire Nighthawks (only 3) in stock.  I made due with what I brought.

2/22: 0-2 vs. Reckoner, Humans, and Aristocrats
        1-2 vs. Bant Populate/Detain deck
        0-1-1 vs. Humans deck with Sigarda, Host of Herons and the 5/3 angel that gets hexproof and indestructible when humans are in play and MAINDECK Witchbane Orb... ARGH!!!
        2-0 vs. green ramp deck.

Surprises: 
0. Being able to get Liliana's ultimate off fairly reliably.  I figured I would be using her -3 ability a whole lot more than I did. 
0.5.  Being able to chain multiple Diabolic Revelations. 
1. Losing despite being able to chain into multiple Diabolic Revelations.  Hexproof is a pain in the rear end. 
2. The number of fog effects being used in the metagame.
3.  A notable lack of red decks to beat up on.
4. How good Trading Post is when you're facing down non-trampling super-beef.  An 0/1 Goat for 1 life that dodges sorcery-speed removal.  Gaining life at the cost of the extra cards you 'draw' off Liliana.  Nullifying  Boros Reckoner very effectively.  Pleasantly surprised.
5.  How crappy my Nightveil Specters were.  They whiffed so much of the time, I am contemplating dropping them.  I think I want some Crypt Ghasts, but couldn't figure out where to put them until Nightveil Specter's sub-par performance.  They would probably be a tad better if I had more ways of protecting them, or at least getting them back.

Observations:
1.  I really, REALLY need Sign in Blood and Elixir of Immortality (or Psychic Spiral or both).
2.  I really enjoy this deck.  Creating hilarious board states where I'm attacking with 2 Vampire Nighthawks, one of which is a 13/14, and 3 Nightveil Specters, while holding the other 3 creatures in my deck back on defense is an absolute blast.  I got more than a few jaw-drops in that game.  Of course it didn't do much though... I attacked into a Fog.
3.  I think I want 1 Rakdos Charm maindeck over a Beckon Apparition since it kills artifacts.  That's just randomly good some of the time.  Also, the last ability can burn people out if I'm crazy lucky.
4.  Mutilate would be really good.
5.  Not being able to reload after chaining Diabolic Revelations makes the game very difficult... You really have to be careful and think about what you're tutoring up, and how many cards you tutor for.  Getting blown out by a Fog when you pump your Nighthawks with Lilianas sucks.

Changes:

1.  SIGN IN BLOOD!!!!!
2.  Rakdos Charm
3.  Elixir of Immortality
4.  1-4 Trading Post maindecked
5.  Gateway Shade?
6.  Crypt Ghast?
7.  Mind Grind?
8.  Psychic Spiral?
9.  [insert name of useful artifact creature] to power up Trading Posts?
10.  Ring of Xathrid?
11.  Mutilate?
12.  Reliquary Tower?
