Artisan's Sorrow

Naturalize sets the floor: two mana, instant speed, destroy an artifact or enchantment, end of card. This doubles the price and answers the obvious question (why pay four for what green prints at two?) with one thing the cheaper version cannot offer: the Scry 2 stapled onto the back. That scry is not card advantage and does not pretend to be; the spell still trades one-for-one against whatever it kills. What it buys is selection at exactly the moment selection matters. Because the destruction half is reactive, you are answering a permanent that already exists, the spell tends to resolve when you most need to know what is coming next, and the look at two cards tells you whether to dig for a threat, find a second answer, or shove a dead land to the bottom. Both halves operate at instant speed, so you can sit on it, let an artifact or enchantment commit to the board, and answer on the opponent's end step or in response to an activation while smoothing your next draw either way. The premium over Naturalize is paid entirely for that smoothing. A four-mana removal spell that only destroyed would be unremarkable green disenchant tax; the value lives in turning a moment you were forced into spending mana reactively into a moment you also get to plan your next two turns.
