Well I like the idea of Sadistic Sacrament in a deck like this as the deck is easily capable of producing the BBB it requires (don't know if it should be a 4-of, though), but I think the deck should be even more combo orientated. I would cut out the Goyfs (good SB addition, though), Hymn (replaced by Duress) and Gatekeeper.
I'd much rather have Tendrils as an alternate win condition than creature beatdown.
I'm currently goldfishing a list that looks like this:
Draw:
4 Dark Confidant
1 Ancestral Recall
3 Night's Whisper
1 Necropotence
Tutoring:
1 Demonic Tutor
1 Vampiric Tutor
1 Demonic Consultation
3 Grim Tutor
2 Crop Rotation
Disruption:
4 Duress
3 Cabal Therapy
1 Hurkyll's Recall
Win:
1 Time Walk
1 Tendrils of Agony
4 Vampire Hexmage
2 Dark Depths
1 Yawgmoth's Will
Mana:
4 Dark Ritual
3 Cabal Ritual
1 Black Lotus
1 Mox Jet
1 Mox Sapphire
1 Mox Emerald
1 Lotus Petal
1 Bayou
3 Bloodstained Mire
3 Polluted Delta
1 Strip Mine
1 Wasteland
3 Underground Sea
2 Swamp
I like the deck, just not for me. I don't like to play combo, I lean to more of a fishy style of play.
The original purpose of my deck was to abuse Sadistic Sacrament, In an Aggro/control sort of way. When I saw these new cards and the interaction with Dark Depths, I liked this as a quicker kill than I had and sort of made it fit, There is way more room for tweeking.
The gold fishes I have had have been very varied with turn three 20/20 attacks or turn 1 thought seize, Null Rod, Sad Sac. Very varied hands and very powerful, but completely different routes to victory.
Any thoughts on the deck list, and I really want to of the GY hate cards from my SB in my main

not enough room.
