not sure about Despise , pulling creatures is nice, but Cry of Contrition , Thoughtseize , Raven's Crime or Inquisition of Kozilek may fill that slot better. as for draw, i would probably play Abzan Charm (power of modes) or Altar's Reap (sac/persist to dodge spells) over Read the Bones (sorcery speed scry/draw).

Vampiric Rites may be another option as enchantments are harder to remove in most cases, and is a sac outlet that draws and gains life. Blasting Station is another option.

Sigil Captain may be a way for you to have more Melira, Sylvok Outcast in your deck as the persisted creatures are 1/1s.

what do you need white mana for? I'd cut all the cards that produce white mana and increase all the swamp and forest lands.

@Izu_Korasu and @kamarupa

6 years later and I am back to Tappedout. I quit mtg quite soon after planning this deck. Anyways thanks for all the suggestions!

Blasting Station and Vampiric Rites are definitely going in if I ever actually build this. On the other hand there might have come a lot of new cards that could interact even better. More updated suggestions are always welcome.

@kamarupa: yes, cutting out white makes all the sense!

MortisAngelus maybe keep the white mana and add in Geralf's Messenger and Solemnity - that combo with Viscera Seer and Altar of the Brood is disgusting. Also, Hall of Heliod's Generosity and Mastermind's Acquisition . You can actually drop green/Melira in favor of Solemnity.
