Petrified Hamlet

Most land-hate answers the land as an object: Wasteland cracks the nonbasic, Ghost Quarter trades one-for-one, spot removal picks off the creature-land the moment it swings. None of that touches the utility land that never dies to anything because it just sits back and taps for something dangerous. This attacks that category on a different axis. Naming a land at entry does two things at once: it staples a plain ability onto every copy of that name, and it switches off any non-mana activated ability across the game that shares it. The named land keeps everything else: its triggers, its statics, its printed mana, its existing colored ability if it has one. What it loses is the button that made it worth playing. A creature-land can no longer animate; a filter land that draws or recurs stops drawing or recurring; the loop land can't loop. The mana-ability carve-out is the deliberate ceiling. Aim this at a genuine dual and you barely inconvenience anyone, because the dual's whole job is mana, and mana abilities are exactly what stays online. It bites the lands whose value lives in an activated ability, not in fixing. And because the name is chosen once at entry and never rechecks, it punishes redundancy: run four of the same engine land and one naming shuts all four off; keep a singleton toolbox of different names and this catches whichever one you happened to guess. A colorless source that also draws a bead on a specific land stakes out a lane most land-hate has never bothered to work.
