Casualties of War

The permission slip is the whole design. Modal spells usually make you pay for flexibility by capping how much you can pick, but this one inverts the deal: every mode you choose adds a target, and choosing all five wipes out an artifact, a creature, an enchantment, a land, and a planeswalker in a single sorcery. The friction that keeps six mana honest lives on the board, not the card. Casualties reads like a blowout on paper, yet its ceiling depends entirely on your opponent having presented five distinct permanent types to hit; against a lean aggressive board it might do nothing but kill a lone creature and shred a land, functioning as an overpriced two-for-one. That gap between floor and ceiling steers it toward Golgari specifically: black and green both traffic in unconditional destruction, so the color pair can service every mode without splashing, and the sorcery timing plus the steep double-pip cost mark it as a top-end payoff rather than reactive interaction. Its closest kin are the sweeper-adjacent "destroy each" effects, but this is surgical rather than symmetric; you never blow up your own board, and the land mode in particular gives it a Sinkhole-plus-removal profile that fair midrange rarely wants to answer through. It is a haymaker built for the deck already grinding, not the one trying to stabilize.
