Cleansing Meditation
Mass enchantment destruction is white's home turf, but the threshold clause is what turns this from a symmetric sweeper into something that breaks parity. The base mode is the catch-all wipe: clear every enchantment on both sides of the table. Hit threshold and the same spell that destroys the board hands back only the enchantments it just killed, walking you out of a mirror-image wipe ahead of where you started. The fine print is precise about this: it returns the cards "destroyed this way," meaning the enchantments that were on the battlefield when you cast it, not whatever enchantments were already sitting in the bin. So the reward scales with how committed your own enchantment side is when you pull the trigger, which inverts the usual instinct. You do not want to cast this as a panic reset; you want the board developed, your auras and global enchantments down, theirs alongside, before you sweep and reclaim. White reanimation is deliberately scarce, and recovering the enchantment half of a board at sorcery speed by routing through destruction is a genuinely odd side door into that space. The catch is timing rather than cost: the threshold half only comes online after you have done the graveyard work, so the spell asks you to grind first and reap second. It reads as a clever toolbox piece more than a reliable answer, because decks that just want enchantments gone rarely want to wait to earn the reanimation upside.
