The core of this deck still remains the same, value from graveyard and big bad bodies, but some of the pieces have changed. Overall I feel this deck moving much more towards taking advantage of being able to apply early pressure, finish with some big threats, and avoid fizzling out. I think there are still some adjustments to the main to streamline things more but I'm not unhappy with where it is at.
Rampant Growth is long gone for more proactive cards, it was nice to fetch a land but the fixing wasn't relevant enough to warrant doing nothing for a turn often. Prey Upon has been cut as being too cute, throwing a deathtouch guy at a threat was always sweet but I would almost always prefer paying another mana for straight removal, currently Drown in Filth is working as my removal as it hoses regeneration and fills the yard, I may be jamming in some better spot removal soon though.
The other Prey Upon slot was given to another copy of Viscera Dragger, a card I haven't had the chance to fire off much but I think has real potential. Undead Servant is another card I'm really wanting to be good in this deck. The match up I think I need the extra bodies most, mono black control, can just wipe not only the servant but all his little buddies too with Evincar's Justice.
Prey Upon was cut also in concession to possibly getting rid of Sedge Scorpion in the near future. It is nice against creature based match ups but Young Wolf is coming in a lot more often and being a lot better in the control match ups.
Lastly we have Recover being cut for Tortured Existence. While I have no fantasies of turning this into an engine revolving around it, I do like the set-it-and-forget-it role of it in this deck. I can use it to provide or return Undead Servants to/from the graveyard, dredge a Stinkweed Imp and then trade it back for the best creature I just flipped over, set up a Sedge Scorpion scavenge, and other neat things. I don't think that it creates any new angles for this deck but allows it to keep going longer than any other Recover kind of spell.
