Vampire Warlord
A 4/2 body asks to be killed, and this card answers by turning the rest of your board into a renewable shield. The regeneration here is not a one-time safety valve bought with mana; it is gated behind a sacrifice, which means every other creature you control is a stored block. Feed one to the warlord and it shrugs off a combat trade or a kill spell, taps down, and comes back clean. That cost structure is the whole strategic point: the warlord wants a wide, expendable board around it, the kind of token-and-fodder shell that aristocrats decks already build, so the sacrifice fuel costs you little and the regeneration costs you nothing in mana. The body itself is fragile, four damage on a frame that dies to almost anything, but the regeneration clause rewrites what that fragility means while you still have bodies to spend. The catch lives in the regeneration rules themselves: it taps and removes the warlord from combat, so saving it mid-attack means it stops attacking, and it does nothing against exile, sacrifice effects, or bounce. As a piece of color-pie work it reads as classic black: life and bodies are currency, and survival is something you purchase by spending the lesser creatures around you.
