A GB Sac deck that primarily uses eldrazi spawn and scion generators as a way to generate value off of Carrion Feeder, Bloodbriar, and Nantuko husk.

Card Breakdown

Bloodbriar: The star of this deck. It's incredibly easy to generate value out of this card, and it can easily get as big as a 7/8 against removal-light decks. It triggers off of Carrion feeder, Nantuko husk, eldrazi tokens, and even evolving wilds, which makes it surprisingly easy to grow into your biggest threat.. The fact that it can buff as a result of Carrion Feeder or Nantuko Husk buffing themselves can lead to more difficult blocking choices for your opponent. This card has quickly become one of my favorite pauper cards, and I hope it can at least find a place in a tier 2 deck.

Carrion Feeder: One of the deck's other primary beaters. It grows less than husk per sac, but gains counters instead of a temporary buff and can come out on turn 1. One of this deck's most powerful plays is a T1 Carrion feeder into a T2 young wolf, which is sacced to Carrion feeder to give you 2 2/2's on turn 2. Since it can take a couple of turns to get going, you're sometimes better off using a Carrion feeder that you draw late or duplicate feeders to buff a feeder or husk that you already have out.

Nantuko husk: Nantuko Husk plays a similar role to Carrion Feeder, only more explosive, since it gains temporary +2/+2 buffs instead of +1/+1 counters.

Blisterpod, Young Wolf: Probably the best sac targets in the deck. Blisterpod can provide two sacrifices, and mana if need be. Young wolf usually only provides 1 sacrifice, but the undying makes it a threat after you sac it. One of my favorite things with this deck is when you get a turn 1 carrion feeder into a turn 2 young wolf for 2 bears on turn 2.

Nest Invader, Scion Summoner: Decent bodies that provide a sac target. Scion summoner is usually just a worse nest invader, since you don't often attack with the 1/1 token, but that still makes it extra copies of nest invader.

Vulturous Aven: This card has done a surprising amount of work. A 2/3 flyer that can draw 2 cards is great when you're just about to win, being able to swing in for that last bit of damage.

Rite of Consumption: A good finisher if we can't push through that last bit of damage.

Rancor: It's rancor. It pushes through more damage, which is great in our deck because none of our dudes have trample. I'm heavily considering adding 2 more copies, as it's just so good at getting damage through.

Tragic Slip: So good in this deck. It's practically unconditional removal unless you're so far behind you've probably already lost. Even just sacrificing an eldrazi for mana to trigger morbid is still worth it, and if you have a carrion feeder or nantuko husk out then that's even better. Can sometimes be a little awkward if you want to cast it on their turn and only have a husk or eldrazi token out, but even then it's still usually in your favor.

Unearth: Can be used to get back any creature in your deck other than Vulturous Aven, so you can get back a young wolf or blisterpod to keep your engine going, or get back a bloodbriar that they spent a removal spell on. Cycling ensures it's never a dead card. Considering running 3 or 4, not sure yet, as it's not as good if you don't already have a target, making it a better draw mid-late game.Khalni Garden: Provides a token for sacrificing at the cost of being a tapland. Only a 2 of since this deck is fairly aggressive, but it's not often that it ends up screwing me over.

Evolving Wilds: The primary mana fixing. In case you didn't realize, it also triggers Bloodbriar, which is why we run it over gainlands. We don't want both since this deck is fairly aggressive and too many taplands can screw us over, and I decided being able to buff bloodbriar is more important than the lifegain. Since the deck is only two colors, it's not often that a tapland would provide better fixing anyways.

Sideboard

The sideboard is almost entirely matchup specific removal. Doomblade, Dead weight, and Epic confrontation are all good removal against creature heavy decks, Naturalize gets rid of enchantments and artifacts. Relic is obvious tech against graveyard decks, and Duress is good against control decks to get rid of their better cards. I'm less sure about the sideboard than the mainboard, and definitely feel that it could use improvement. Sprout Swarm is great for longer matchups as it ensures you always have something to sac.

Maybeboard

Gavony Unhollowed: It seems like it would be an autoinclude, but I feel like it's just too slow. You can't get it out until turn 4, and by then you could easily have a giant carrion feeder and bloodbriar. It's P/T ratio doesn't do it any favors, as you can probably only tick it up once or twice when you get it out, and that's just not enough. Additionally, I feel like the deck currently already has a good balance between sac outlets and sac targets and this could upset that if we removed something like Scion Summoner (probably the most likely candidate for cuts if I do decide to add this) it weakens that balance.
