Mass Calcify

The wrath that takes sides. White board sweepers had long been color-blind by design: the canonical mass-destruction spells erase your own creatures alongside the enemy's, and the cost of resetting the board is that you reset yours too. This one rewrites that contract by exempting your color outright. Played in a mono-white shell, it reads as one-sided removal at sorcery speed; played anywhere else, it is a sweeper that happens to spare any white creatures still on the table, yours or theirs. That asymmetry is bought with a steep price and a hard restriction. Seven mana is well above the going rate for a sweeper, and the exemption is fixed to a single color rather than something you can engineer mid-game, so the card only pays off when you have committed to building around its blind spot. Outside a white-dominant board it collapses back into an expensive symmetrical wrath, which is the design's honest tax for the upside it offers when the deckbuilding lines up. The result is a sweeper that asks a question most sweepers do not: not "is the board bad enough to reset," but "is my board the right color to survive the reset I'm about to cast."
