A five-mana enchantment with no immediate board impact is a test-only sacrifice payoff; the once-per-turn cap limits its ability to take over games.

Could be wrong if Revealed sacrifice density may conceal a strong Standard shell that reliably turns the first post-cast death into major value.

Pioneer demands faster impact than this conditional five-drop provides. It can generate value in dedicated sacrifice lists, but needs setup and survival.

Could be wrong if An established sacrifice shell may value the free creature deployment enough to tolerate its mana cost.

Five mana, no immediate effect, and a once-per-turn trigger are far too slow for most Modern decks, even if creature deaths are available.

Could be wrong if A resilient creature-combo deck could make the trigger materially stronger than its fair-rate floor suggests.

Legacy's cheap interaction and speed make a five-mana conditional enchantment implausible; it lacks the immediate payoff or uniqueness needed to justify it.

Could be wrong if Fast mana plus a dedicated sacrifice engine could create a narrow but viable fringe application.

Aristocrats decks can turn recurring nontoken deaths into substantial creature value, but five mana and one trigger per turn keep it a specialized inclusion.

Could be wrong if Creature density and reliable sacrifice outlets may make it a stronger engine than its delayed first trigger implies.

At five lands it will usually replace the first nontoken creature that dies each turn with a free creature, creating a powerful grindy engine after setup.

Could be wrong if Unknown speed, removal, and archetypes may make a five-mana non-board-impacting rare too slow or difficult to exploit.
