This devastating land-denial lock turns every land on the board into a fragile casualty of war. Urborg, Tomb of Yawgmoth quietly transforms every single land into a Swamp, which Kormus Bell simultaneously brings to life as 1/1 creatures. Enter The Flesh Is Weak, whose static ability levies a permanent -1/-1 penalty on nonartifact creatures, instantly shrinking every newly animated land to 0 toughness and sending it straight to the graveyard as a state-based action. Because The Flesh Is Weak only grants the artifact type to creatures that already bear +1/+1 counters, your own lands perish right alongside your opponents' unless protected, effectively locking down all nonartifact land drops and locking your opponents completely out of the game.
