Mystic Melting

Naturalize and Disenchant set the baseline for green and white artifact-and-enchantment removal, and the long design conversation since has been about whether to charge more mana for the same effect in exchange for a rider that softens the tempo loss. This is one answer: the destruction is unconditional and instant-speed, but the card you get back does not arrive until the next turn's upkeep. That delay is the whole bargain. A delayed draw is strictly worse than a draw now, so the deferral lets the spell carry card advantage that an immediate-draw version at this cost could not justify. In practice it means you are never down a card for cracking an opposing Pithing Needle or sweeping away an enchantment lock, but you also do not refuel the turn you spend the mana, which matters in any race where the tempo of the swing decides the turn. Reactive green has always wrestled with the same problem: it wants to interact with the artifact-heavy and enchantment-heavy decks it otherwise loses to, without bleeding the cards that interaction costs. Most green disenchant effects answer that by stapling the draw to a creature body or a sorcery-speed clause. This one keeps the instant timing and pays for the card with patience instead.
