Primevals' Glorious Rebirth

Seven mana to return every legendary permanent card from your graveyard at once: not just creatures and planeswalkers but legendary artifacts, legendary enchantments, the saga that already finished resolving, the equipment that died with its bearer. The reach is total, and the sorcery-speed price is the obvious brake, but the real constraint is the deck it demands. A pile of generic threats gets nothing from this; it only pays off if your graveyard is stocked with named permanents worth a second life, which forces a singleton-heavy, legend-dense construction around it. That construction is what turns it from a recovery spell into a whole archetype's payoff. Where mass reanimation like Living Death or Patriarch's Bidding rewards creature-tribe glut, this rewards the opposite: a roster of unique, high-value permanents you were always going to play one copy of anyway. The casting restriction that gates every legendary sorcery (a legendary creature or planeswalker already in play) folds neatly into that, since a legend-dense board almost always meets it on its own. What emerges is a finisher tuned for the games that have already gone long: you commit to legends, watch them die to removal and trades across a grind, then pay seven to bring the entire fallen court back simultaneously. It is the spell that converts a battlefield full of corpses into a battlefield full of bombs, and it only makes sense in a deck built to fill that graveyard with the right ones.
