Builder's Bane

The doubled X is the design tell: red rarely gets to scale a single spell against a board of artifacts, and paying twice for every target is the brake that keeps the rate from collapsing into a cheap sweep. Each artifact you name costs two mana, not one, so this is a heavy hammer rather than a swift broom. The damage clause is what lifts it above clean removal. It fires at each player equal to the number of artifacts they controlled that were lost to the spell, which ties the size of the burn directly to your target selection. Point a fat X at an opponent's artifact stockpile and the spell doubles as a finisher: the player who controlled the pile takes damage proportional to what you just shattered. The math rewards careful aim, since you destroy exactly the X artifacts you choose and the controller of each one pays for it in life. This is a removal-and-burn hybrid where one decision sets the size of both effects at once, an early answer to the problem of red lacking a scalable response to a developed artifact board. The symmetry only bites you if you feed it your own permanents; left to its natural use, it is a one-sided sweep that bills the artifact player for the privilege of having built the board in the first place.
