Kormus Bell + Urborg, Tomb of Yawgmoth + Night of Souls' Betrayal

Kormus Bell

Urborg, Tomb of Yawgmoth

Night of Souls' Betrayal

How it works

1. When a land enters the battlefield, it becomes a Swamp due to Kormus Bell. This then causes it to become a 0/0 creature due to Urborg and Night of Souls' Betrayal, and die as a state-based action due to having 0 toughness.

This brutal lockdown relies on a passive global transformation, turning every land on the battlefield into a fragile target. Urborg, Tomb of Yawgmoth ensures every land is a Swamp, which Kormus Bell then animates into 1/1 black creature-lands. Finally, Night of Souls' Betrayal steps in with a continuous -1/-1 penalty, instantly reducing every single 1/1 land into a 0/0 and sending it straight to the graveyard as a state-based action. The result is a total land wipe that permanently prevents any player from developing a mana base going forward.
