ORI: The sacrifice deck

Magic Origins has a number of cards in red and black that allow you to sacrifice a creature, and several other cards that are better if you have access to a sacrifice outlet. Does it have enough cards in both categories to allow for a sacrifice deck? Let’s enumerate the cards in both categories.

  • Cards that allow you to sacrifice a creature:
    • Black: Nantuko Husk, Consecrated by Blood (uncommon), Fleshbag Marauder (uncommon), Tormented Thoughts (uncommon) = average of 5.1 copies in an 8-person draft
    • Red: Fiery Conclusion (uncommon) = 0.9 copies (there’s also Pia and Kiran Nalaar, but that only allows you to sacrifice artifacts)
    • Green: Evolutionary Leap (rare) = 0.4 copies
    • Red/Black: Blazing Hellhound (uncommon) = 0.9 copies
  • Cards that allow you to borrow/steal a creature:
    • Blue: Willbreaker (rare) = 0.4 copies
    • Red: Act of Treason, Enthralling Victor (uncommon) = 3.3 copies
  • Cards that can create multiple creatures:
    • Colorless: Foundry of the Consuls (uncommon), Hangarback Walker (rare) = 1.3 copies
    • White: Murder Investigation (uncommon), Gideon’s Phalanx (rare), Sigil of the Empty Throne (rare) = 1.7 copies
    • Blue: Aspiring Aeronaut, Whirler Rogue (uncommon), Thopter Spy Network (rare) = 3.7 copies
    • Black: Undead Servant, Priest of the Blood Rite (rare), Liliana Heretical Healer (mythic) = 3.0 copies
    • Red: Dragon Fodder, Ghirapur Gearcrafter, Thopter Engineer (uncommon), Flameshadow Conjuring (rare), Pia and Kiran Nalaar (rare) = 6.5 copies
    • Green: Dwynen’s Elite (uncommon), Zendikar’s Roil (uncommon), Nissa Sage Animist (mythic) = 2.0 copies
  • Cards with beneficial effects that trigger when a creature leaves the battlefield:
    • Colorless: excluding Hangarback Walker since it was listed previously, Runed Servitor since it benefits you and your opponent equally, and Guardian Automaton since it only gains you 3 life)
    • White: excluding Murder Investigation since it was listed previously
    • Black: Deadbridge Shaman, Shadows of the Past (uncommon) = 3.3 copies (excluding Liliana Heretical Healer since it was listed previously, and Infernal Scarring since sacrificing the enchanted creatures leaves you a card down)

In an 8-person draft, black has an average of 5.1 sacrifice outlets and 6.3 cards that have synergy with those cards (although 2.4 of those are Undead Servants, which only create more than 1 creature if you have multiple copies). Red is the other color with cards in both categories, and a R/B player has access to an average of 6.9 sacrifice outlets and 17.4 cards that have synergy with those cards.

Many of these cards will be drafted by other players. Let’s assume that there are 3 drafters in each color but no other drafters in this archetype, and let’s try to determine how many of these cards we’re likely to end up with:

  • Nantuko Husk and Fleshbag Marauder will be taken by other black players, but a little less highly. Let’s assume that we get half of the copies of these cards (1.6 copies).
  • Foundry of the Consuls and Hangarback Walker can be played by any player at the table. Foundry of the Consuls is only good in the artifacts and sacrifice archetypes, while Hangerback Walker is a high pick in any draft deck, so we’re likely to end up with 0.5 of these cards.
  • The red and black cards that create multiple creatures are valued by any deck playing that color, as are Enthralling Victor and Deadbridge Shaman. These 12.8 cards are shared by 3 players, so we can expect to get 4.3 of them.
  • We will probably get most or all copies of the remaining cards: Consecrated by Blood, Tormented Thoughts, Fiery Conclusion, and Blazing Hellhound for sacrifice outlets (3.6 copies), and Act of Treason and Shadows of the Past for the remaining categories (3.3 copies).

Combining these number, we find that we’re likely to end up with about 5 sacrifice outlets and about 8 cards that work with them. That’s enough that if we start our draft with a few of the top cards from either of these categories (Fleshbag Marauder, Enthralling Victor, Priest of the Blood Rite, or multiple Undead Servants), then we can reasonably attempt to draft this archetype.
