Stalking Vengeance

The whole design hinges on a single conversion: it turns every other creature death you control into a Lava Spike scaled to the dead body's power. That reframes the entire board as ammunition. A token swarm stops being chump fodder and becomes a stack of burn waiting to fire; a sacrifice outlet stops being a value engine and becomes a Howitzer that ignores blockers, removal, and life-gain race math entirely. The power-not-toughness clause matters: this rewards going wide with hard-hitting bodies, not durable ones, which pushes it toward aggressive aristocrat shells rather than grindy attrition decks. The seven-mana, no-protection frame is the obvious cost; a five-mana removal spell ends the plan before it starts, and the haste on its own body is a small consolation prize that hints at the real intent (the creature wants the board to die around it, not to attack). The targeting is the quietly nasty part: this can point damage at a player or planeswalker, so a board wipe on your opponent's turn, or your own sacrifice loop on theirs, becomes a finishing volley that resolves whether or not anyone is attacking. It is a death-payoff that predates the modern aristocrats vocabulary, doing the work that later sacrifice-matters payoffs would formalize, but with a directness most of them never matched: not drain, not card draw, just damage equal to whatever you were willing to lose.
