True Love's Kiss

White's tax on answering artifacts and enchantments is the whole design conversation here, and the pricing tells you what you are buying. Disenchant does the destroy work for two but leaves you down a card; the lever that separates this one is the extra draw stapled onto the interaction. Four mana buys the removal plus a fresh card to replace the spell you spent, so the exchange stays even on cards rather than bleeding you a resource to answer a threat. What it does not buy is tempo. At double-white and four mana to exile a single permanent, this is a slow, mana-heavy way to solve one problem: it may be an instant, but the cost holds you back until you have the mana open and are willing to break even on cards rather than get ahead. Exile rather than destroy is the other deliberate choice, closing the recursion loops and indestructible dodges that make destruction spells unreliable against the stickiest permanents. It belongs to the more recent impulse to bundle a cantrip onto interaction so removal stops trading down on resources, keeping card parity where a bare destroy spell concedes it. The storybook conceit fits the effect cleanly: a kiss undoes the curse, the enchantment leaves the battlefield for good, and the world corrects itself.
