Urborg, Tomb of Yawgmoth makes every land a Swamp; Kormus Bell turns every Swamp into a 1/1 creature. Make Obsolete then hits all opponent-controlled creatures with -1/-1 until end of turn, which kills every 1/1 land-creature they control and strips their entire mana base in one shot. Black land denial decks running Sheoldred, the Apocalypse or K'rrik, Son of Yawgmoth run this as a one-sided Armageddon that leaves the pilot's own lands intact because Make Obsolete only targets opponents.

Cheaper, tighter, alternate lines

Massacre Girl, Known Killer replaces Make Obsolete as a reusable body that triggers the same -1/-1 wipe on entry, though it hits your own 1/1s too if Urborg and Kormus Bell are in play — sequence carefully or sacrifice the Bell first. Mutilate is the broader sweeper backup in mono-black, but it doesn't single out the 1/1 lands the same way and needs heavy Swamp density to matter.
