Sudden Demise

The color-selective sweeper: name your opponents' hue, scale X high enough to clear it, and if you've chosen a color you aren't playing, your own board walks away untouched. That asymmetry is the whole pitch. Where most red sweepers ask you to overcommit and blow up everything including your own, then rebuild faster than the table, this one lets you keep a developed position while resetting someone else's, provided the opposition has cooperated by playing distinct colors. The constraint is genuine: when several creatures share a color you scour them all for a single casting, but against an opponent splashing creatures across the rainbow, you can only ever address one slice of the board per cast. The X structure makes it a true scaling answer rather than a fixed line, relevant from an early reset against a weenie deck to a late blowout against fattened bodies. Colorless threats and artifact creatures with no color all slip through, and that blind spot is exactly what buys the selectivity. A mono-red removal spell that thinks in terms of opposing color identity rather than raw board state is an unusual shape, closer to a targeted political weapon than a symmetrical Wrath. It rewards reading the color spread before you read anyone's power and toughness.
