Born of the doGs has some pretty awesome cards for mono black and I'm pretty excited for the set. Wizard's has been doing us a solid lately with black cards. Here are some of the main contenders for black in the format.
Bile Blight is a card that doesn't seem to have much use for the format at first. I think that I can be interesting though. It can kill token armies and any utility creatures that have been cloned. Overall it isn't amazing, but if your meta is very token heavy then you should use this card.
Champion of Stray Souls isn't my favorite thing ever. I'm not a rules guru, so if one reads this please clarify, but I'm pretty sure he cannot return the cards that he sacs. This, plus he needs to tap, make him pretty meh. I wouldn't run this card even though it is pretty cool flavor and art wise.
Drown in Sorrow is pretty crazy. It's pretty much Infest with scry. If you can make use of Infest then we have a strict upgrade here.
Eater of Hope might be a little to heavy on the mana side of things. He is a sac outlet and removal all rolled into one though. One would play this card if they were looking for a less broken sac outlet.
Fate Unraveler has a lot going for it. Its a four drop so it works with Dimir House Guard. It drains your opponents life which seems better for a Nekusar deck, but might have some uses in very drain oriented versions of XHD. This is one to watch in the format. It flies under the radar.
Fated Return is just too expensive. Rise of the Dark Realms is much more expensive but the effect is just so much more. I dont see how this one makes the cut.
Forlorn Pseudamma is totally scary. That art is just weird! I think its cool that wizards had the balls to make a card like this though, and I think that it has some potential to see play. It has that magic CMC for Dimir House Guard and it makes tokens. The tokens could always be useful for a more stax oriented deck. Plus it has some evasion. A great card in the right deck.
Gild is amazing. For 4 mana you can just straight exile a creature. Then you get an updated Eldrazi spawn. This gives mono black other answers besides edicts for hard to kill cards. Excellent card that I will try very hard to find room for.
Pain Seer: Bob 2.0. If you can afford to run Dark Confidant you just found some redundancy. A pretty cool card for all formats. It also has two of the best creature types. Pretty cool.
Sanguimancy is pretty awesome card draw. It seems bad early but a huge draw spell in the late game. Might not make the cut, but its one to watch.
I think Sea God's Revenge might have been ok. I considered blue and red for a very long time due to Thassa and Stormbreath. Glad I made the right choice, but that must mean that I played really bad then.
I drafted a lot of 3xTHS lately but I had never tried sealed so yesterday, I was looking for something different and tried a sealed. I joined without any expectations but I didn't want to go 0-3 which I did. I don't think my pool was really bad but maybe I built it wrong. Any opinions would be extremely valuable.
Fate Unreveler If you play Erebos I think you are better off with Underworld Dreams as it gives 3 devotion plus its harder to remove.
Sanguimancy I was pumped to try this at first but the more I look at it, the more it looks like Skeletal Scrying would be more consistent.
Gild This one I will try for sure.
Do you play Ashes to Ashes to answer Erebos?
Bloodstained Mire
Pile B
Karn Liberated
Craterhoof Behemoth
I agree. Fits Theros quite well. But it only has scry 1 IIRC.

This was the deck:
