Blade of the Bloodchief

Most equipment scales with what it gives the wearer up front: a fixed bonus, a keyword, a static buff that arrives the moment you pay equip. This one inverts that contract entirely. It enters small and grows only when creatures die, which means its value is a function of how much killing happens around it, not what you spend on it. On a Vampire the rate doubles, and that doubling is the design's whole intent: it asks for a deck built to feed the graveyard, where chump blocks, sacrifice fodder, and aggressive trades are not losses but fuel. The friction is that an empty board does nothing for it; the engine is dead until the dying starts. What makes the card durable is how it converts attrition into inevitability. In a grind where both sides are trading creature for creature, the equipped attacker is the only permanent compounding from each exchange, turning a stalled mid-game into a clock that nobody else is building. The Vampire clause anchors it to a specific tribal lineage, but the death trigger is type-agnostic, so any creature deck willing to spill blood can run it as a generic counter-accumulator. It is cheap to cast and cheap to move, which keeps it relevant late: when the wearer dies, the accumulated counters are lost, but the next one can start the project anew for a single mana.
