Demolish

Stone Rain with a switch on it: red's standard four-mana land destruction, plus the option to break an artifact instead. The choice is real and occasionally decisive (you never draw a dedicated artifact answer against an opponent who isn't playing artifacts), but the price of the choice is what keeps the card off the short list. Color-pie logic explains why it can exist at all: red is the color that smashes rocks and Mountains, so folding "destroy an artifact" and "destroy a land" into one sorcery reads as clean, flexible disruption. The problem is the rate, not the flexibility. Four mana and a card to remove exactly one permanent is a steep tempo trade in either direction, and both halves are undercut by something more focused. The artifact half is done cheaper and faster by two-mana spot removal that wasn't built to also blow up a land. The land half is done harder by strategies that commit to land destruction as a plan, looping or stacking the effect to build toward an actual lock rather than spending one sorcery on a single tap-land. Removal of this shape sells breadth, and breadth is worth something when you can't predict what you'll need to answer. But the answer it gives you arrives a turn slower and a card heavier than the specialists, and the flexibility never quite pays back the inefficiency it costs.
