Martyr's Bond

Grave Pact taught black decks to weaponize their own attrition: every creature death drags an opponent's down with it. This is the white refraction of that idea, widened past creatures and aimed at the whole board. Because the trigger keys off any nonland permanent of yours hitting the graveyard, the punishment is type-for-type: an enchantment of yours dying forces opponents to sacrifice an enchantment, an artifact an artifact, a creature a creature. That breadth is what white adds to the black ancestor, which only ever cared about creatures dropping creatures. The cost of it is steepness and slowness; six mana for an engine that does nothing until something of yours starts dying means you need a board willing to die on demand, and white is not the color that natively turns its own permanents into ammunition. The reward is an attrition lock that taxes more than just the battlefield's creature count: token generators, planeswalkers that crack themselves, and sacrifice-fueled removal all feed it, and each death can erode a category of an opponent's board they would otherwise consider safe. It asks you to build the death-loop around it rather than slotting it into one already running, and in a multiplayer game the type-matching clause becomes a slow, grinding tax that bends the whole table toward your sacrifice math.
