White's answer to enchantments has always been the broom rather than the scalpel: where green's Naturalize picks off a single target, white sweeps the whole category off the table, indiscriminate and symmetrical. This is that instinct with a small reward bolted on. Because it resolves as a sorcery rather than firing a triggered ability, the life gain is computed once at resolution, counting every enchantment the spell destroys in the same instant it destroys them. The payout scales with exactly how cluttered the board had gotten: the deeper the enchantment pile, the larger the swing, which is fitting, because the deeper the pile the more the symmetry stings. Your own auras, anthems, and pillowfort pieces fall alongside the opponent's, since the spell cannot read intent, and you gain life for those too. That total even-handedness is the constraint holding the rate steady: the lifegain pays you back in proportion to the wreckage, your own board included, rather than rewarding a clean one-sided break. The contingency cuts the other way, too. With no enchantments on the table, nothing is destroyed and no life is gained, so the card asks for a board worth sweeping before it does anything at all. It is a categorical reset whose payout is measured against the size of the mess it just made, on both sides of the line.
