Rushed Rebirth

The wrinkle is that the death you're cashing in doesn't have to be one you cause. You target any creature, yours or an opponent's, and the trigger sits dormant until that creature dies this turn by any means: combat, a removal spell, a sacrifice outlet, a burn spell you cast afterward. This is a setup spell, not removal. It never touches the creature it names; it just waits to convert a death into a body from your library, and it rewards you for arranging that death some other way. The mana-value ceiling shapes everything downstream. You always trade down in cost, so the replacement is smaller and arrives tapped rather than an upgrade, which favors a deck stocked with cheap creatures whose bodies undersell their impact: sacrifice fodder with death triggers, mana dorks, disruptive one-drops. Cast on your own creature in front of a lethal block, it turns a chump into a fresh tapped threat and a full library search. Cast on an opponent's attacker you plan to kill in combat, it lets you pay for the block twice. Instant speed is where the card breaks from the sorcery-speed reanimation Golgari usually gets: you can respond to a removal spell already on the stack, ambush a combat step, or hold it up as a bluff and only commit when a death is imminent.
