Seal of Primordium

Naturalize spends its mana the instant you cast it; this banks the green ahead of time, leaving a quiet permanent on the battlefield and holding the destruction in reserve until an artifact or enchantment you actually want gone resolves. The design recasts a one-shot effect as a permanent you prepay and crack later, the green-aligned member of a small family that handed each color its own banked answer. The trade is precise: you sink the mana early in exchange for a destroy effect that costs nothing the turn you spring it. That timing matters more than the raw rate. A telegraphed enchantment sitting in play changes how an opponent commits their own equipment or aura, and the sacrifice is an activated ability rather than a cast spell, so it fires at instant speed the moment a fresh threat lands, with no spell on the stack for a counter to answer. The cost is rigidity. Once it is down the mana is spent, and it can only ever destroy an artifact or enchantment, never tucked away, never repurposed, a single charge waiting for the right target.
