Blood Vassal card art
Blood Vassal enters as a 2/2 and sacrifices to produce two black mana — free acceleration stapled to a body, payable whenever you need it. Mairsil, the Pretender is the deck that wants this most, caging the activated ability and generating two black mana on demand without ever needing the creature in play.

Blood Vassal is a Commander card through and through — the sacrifice-for-mana effect is too slow and too low-impact to matter in Legacy or Vintage, where faster mana exists at no cost. Pauper is the one non-Commander format where it's legal and conceivably playable, though black sacrifice synergies there have better options at common. The card earns its slot almost exclusively in Commander, specifically in Mairsil, the Pretender lists where caging Blood Vassal converts a vanilla 2/2 into a reusable mana engine.

Price Context

Current price

$0.19 bulk tier

At $0.19, Blood Vassal is deep bulk — a throw-in rather than a purchase. That price is stable; there's no pressure driving it up, and its narrow application keeps demand low outside of Mairsil lists.
