Here we are. Right away: This will not include card suggestions for the Jund Version. Replace Village Rites with more Unlucky Witness, Stitcher's Supplier, or Rotten Reunion, switch around how many of these, that's about it. The decks's in a comfortable spot, if a bit slower in the version I ended up going with posting.
That being said, this is going to be a list of cards that can fit into this deck, but would create the need to adjust and tweak the entire thing into something a little more powerful, but less easy to work off of:
Cryptbreaker: Was and still is a heavy contender. I've settled on 1x, but wasn't able to use its abilities as consistently as I hoped. Drawing a card before sacing the Zombies you used it for is a powerful value-play. I've also felt that that bit of additional carddraw wasn't needed as often as another sac-outlet, which is why I've added the simplified Village Rites for it in the final list. If adjustment of this list requires something more value oriented, this is a must to consider.
Zulaport Cutthroat, Thoughtseize, Priest of the Haunted Edge, Voldaren Bloodcaster
and Mausoleum Secrets are all cards I don't feel I need to comment on.
Braids, Arisen Nightmare: I've thought about it, I want to list her. There might be some potential here, but I'm mostly mentioning her for the fun factor.
Teachings of the Kirin
: HIGH on the list. If not our Priest, we finish games with a big enough Woe Strider/board presence overall to close out games. If it weren't for that, this card would be out. Early game the +1/+1 counter isn't anything to write home about, almost makes this card too bad, if you could skip it this card would be glorious. But it mills, taking away card:Sticher's Suppliers job and opening up space to play Village Rites instead of Deadly Dispute to make us quicker, and effectivly creates 2 creatures to sac. One of which with an upside.
Cult Conscript: Now we get into the big contenders, a high contender if you're running Meathook Massacre which I will get into after this. I haven't seen anyone play this with Woe Strider. This card has been printed as a rare multiple times, you could compare it to Bloodsoaked Champion best. You can build decks for both, and can make the argument for both, it's just interesting that this one is an uncommon. Sacrificing a goat activates Conscript, and then you can just keep recasting since a goat died that turn. This is both a value play and especially noteworthy with Meathook Massacre. If there are or will be "Whenever a creature dies add 2 mana" effect in the future, this is an easy instawin combo with Meathook, Bastion of Remembrance and so on.
The Meathook Massacre: My precious. Still.. let me check.. 40 bucks. It is the one. It belongs in this deck. I've only left it out because simplicity, but it belongs in this deck. For instance, the current version I am actively playing has cut Deadly Disputes to make room for the Massacre on curve. Life's full of though decisions like that, including this card is not. Even without the Conscript-Woe interaction I just mentioned, the removal, the lifesteal, the lifegain makes this an insta-include. 2x please.
Fiend Artisan: Safe the best for last. Not because it's my favourite, but it's the most to talk about. I contemplated adding Artisan in the first draft of this deck and even then I already decided against it. It's simply not as smooth. There isn't the mana or value in terms of sac-fodder to fetch something with it and go as wild with Priest as with this version.
That being said, at the same time, there is incredible potential. I've seen that this card has since picked up popularity in a modern version of this deck, and rightfully so. It might be better in modern, in here I think it depends on when and with how many copies you create a consistently empty board on your opponents side so there are no blockers in the way. I consider huge creatures without trample to almost be worthless, and I expect there to be too many situations where it's that other creature you need to sac to get Priest going. First testing and my gut feeling included, in my opinion 1x should be the way to go here, should you include it.
