Finale of Eternity

Two spells welded together at a threshold, and the threshold is set deliberately high. At ordinary X values this is scalable spot removal that can spread across three separate bodies, priced off toughness rather than power so it kills the wide-and-thin creatures that dodge power-based sizing while still respecting the usual constraints: it destroys and it targets, so indestructible turns it off and hexproof denies it a legal target entirely. The reward clause turns the card into a build-around, and it is strictly binary: push X to exactly ten or more and the same spell that clears the board hauls your entire creature graveyard back in one motion. Below ten, you get nothing but the destruction. That cliff is the tension the design is built on. Ten toughness of removal is already an enormous mana commitment, so the mass reanimation is not a rider you stumble into but a payoff you have to engineer, usually with cost reduction or a ritual-fueled burst turn to clear the ten-point bar in a single cast. The elegance is that both halves share one input: the number that measures how much you can destroy is the same number that decides whether the graveyard comes back at all. It sits in the black tradition of finishers where the removal and the reanimation are one gesture rather than a choice between them, and in the scalable-X sorcery lineage that lets a single card be a cheap answer early and a game-ending swing later. The second half only wakes up once you have paid the full toll to earn it.
