Urborg, Tomb of Yawgmoth makes all lands Swamps; Kormus Bell turns all Swamps into 1/1 creatures; Aether Flash deals 2 damage to every creature that enters, killing each incoming land before its controller can use it. The lock is symmetrical and absolute — no land survives entering while all three are in play, which means the deck running this needs its mana established before Kormus Bell resolves.

How it works
01
Prerequisites
—
02
Steps
- Whenever a land enters the battlefield, it enters as a 1/1 Swamp creature due to Urborg and Kormus Bell.
- Aether Flash triggers, dealing 2 damage to the land.
- The land dies as a state-based action due to having less than zero toughness.

Result
Destroy all lands that enter the battlefield; Lock; Mass Land Denial
Variations
Cheaper, tighter, alternate lines
Kormus Bell is the irreplaceable piece; there is no substitute that animates all Swamps. The combo slots most naturally into Rakdos or mono-black-red lists that can win through non-land mana like Mana Crypt, Sol Ring, or Cabal Coffers activations banked before the lock goes up — Ob Nixilis, the Fallen and Ankh of Mishra stack additional land punishment on top if the shell wants redundancy.
