Deck Magic the Gathering : Queen of the Golgari

This is my Savra EDH deck.  The idea is to control the board through Savra's triggered "edict" ability.

Disciple of Griselbrand, Nezumi Bone Reader, Viscera Seer, Hell's Caretaker, Golgari Guildmage and Krovikan Horror all provide the ability to sacrifice creatures.  As a result, this deck is vulnerable to cards that can disable creatures activated abilities.

For easily returned black creatures, the deck has Nether Traitor, Bloodghast, and Reassembling Skeleton.

There is a sub-theme of utilizing the graveyard through Oath of Ghouls, Oversold Cemetery, Splinterfright, Genesis, Eternal Witness, and various dredge cards.  This deck is vulnerable to graveyard removal.

The deck is also good at searching for answers (Shriekmaw, Acidic Slime, Viridian Shaman, Massacre Wurm) through Survival of the Fittest, Birthing Pod, and Worldly Tutor.

I would like to add some cards (Ashnod's Altar, Vampire Hexmage, and Skullclamp), but I'm still thinking about what to take out.  I might also replace Nezumi Graverobber with Scavenging Ooze.
