Terrageddon runs Sylvan Library, Mox Diamond, and Seal of Cleansing as prime Naturalize targets, and stripping Sylvan Library slows their card advantage engine considerably before an Armageddon locks the game down. Pyroclasm cleans up their small creatures like Weathered Wayfarer and Werebear before threshold turns on. Daze and Mana Leak are weak once Armageddon strips everyone's lands and the game becomes a topdeck war, while Wonder and Waterfront Bouncer also trim down. Try to keep Wasteland available to blow up their Treetop Village or a key nonbasic before Armageddon locks in a land-light board.
