Basically the goal of the deck is to get a few blood artists/ cruel celebrants into play along with a sac outlet. Previously in the deck, you had to be very conservative with your attacks and blocks, so you had to take more damage and deal less. Now, with some of the changes that have been made, you can play a little more aggressive, but still fairly conservative.
You are looking to play to your outs with this deck, because even if all of your creatures are gone, we have Rally the Ancestors to bring everything back to the field and sac it one more time. You can play Rally at Instant speed, so if you need some blockers and you have 4 mana available, you can rally those creatures into play to help you block. Rally the Ancestors says to Exile the creatures at the beginning of your next upkeep, however, if you were to sac those creatures and have them in the graveyard instead of the battlefield, they will not be exiled. You can Rally on their end step and do it again on your turn if you happen to have 2 Rallys in your hand.
One of the cards that I am unsure about is Pawn of Ulamog. I like the idea of getting eldrazi spawn tokens whenever my non token creatures die, giving me more things to sacrifice and possibly some more generic mana if I need it.
Yawgmoth, Thran Physician has also been a great addition to the deck. It's another sac outlet and card draw engine. We are not too worried about losing the life via Yawg, because we are gaining life with the BA/CC triggers. He also has pro humans, which is great with one of the top decks being played in modern being humans.
Carrion Feeder has also been a great addition to the deck. There have been games where I have been at low life and my opponent has started to let carrion feeder in for some damage. You can swing with carrion feeder at just a few counters. Whether they block Carrion Feeder or not, you can activate the sac ability at instant speed. If they do block, they lose their creatures, if they don't block, you get in for a ton of damage. You will also get in for more damage if you have any Blood Artists or Cruel Celebrants in play.
Always looking for suggestions and I am looking forward to play testing them.
