Natural State

The mana-value clause is the entire negotiation. Naturalize and Disenchant answer any artifact or enchantment for the same color and roughly the same cost, but they answer everything: the equipment, the enchanted land, the eight-mana payoff. This trades that reach for a sharper price, capping at mana value 3 to refuse the big-ticket targets. The logic is straightforward green deckbuilding economics: the cheapest, most consistently abusive artifacts and enchantments live at the bottom of the curve, so an answer that can only touch the bottom of the curve still catches the things that demand catching while paying less for the privilege. That ceiling is what keeps green's permanent removal honest within its color pie: green is allowed to break artifacts and enchantments, but it is not supposed to have a clean, one-mana answer to a top-end bomb. The card sits squarely in the lineage of instant-speed green disruption that stretches back to the earliest sets, and like its predecessors it lives and dies at instant speed, holding open for the moment the artifact taps or the enchantment resolves rather than committing on your own turn. Against a field of one- and two-mana payoffs it is functionally a strict upgrade on the older catch-alls; against anything that costs four or more it is a dead card, and that line is precisely where the design wants it.
