Fear of Death

Aura removal that scales with your own graveyard, and the self-mill is not just fuel for the effect: it is the whole mechanism. Cast this early and it might shave a point or two of power off a creature, barely a speed bump. Cast it into a graveyard already stocked with a dozen cards and it strips the target of most or all of its offense, turning a would-be attacker into a wall that can no longer bite. The design ties the removal's strength to a resource that naturally grows over a game and that you can push faster with mill effects, so the same two-mana Aura reads as marginal in an aggressive shell and as a hard shutdown in a mill-adjacent one. The catch built into the shape is that it only touches power, never toughness, so it neutralizes attackers but leaves blockers standing and does nothing against abilities or evasion that do not care about combat math. That makes it a soft answer that scales toward hard: a removal spell whose ceiling you build toward rather than pay for up front, and whose floor is low enough that it lives or dies on how much you are willing to feed your own graveyard.
