Glacial Chasm + Walk-In Closet // Forgotten Cellar + Exploration Broodship

Glacial Chasm

Walk-In Closet // Forgotten Cellar

Exploration Broodship

How it works

1. Play Glacial Chasm either from your hand or from your graveyard.
2. When Glacial Chasm enters the battlefield, its second ability triggers, causing you to sacrifice another land you control.
3. Play any land from your graveyard.
4. At the beginning of your next upkeep, Glacial Chasm's cumulative upkeep ability triggers, allowing you to choose not to pay the cost and sacrifice it instead.
5. Repeat.

This clever loop completely locks opponents out of damaging you by leveraging Glacial Chasm to prevent all damage, letting its cumulative upkeep sacrifice it when the life payment gets too steep. Exploration Broodship steps in as the engine's core, allowing you to continually cast that very same land from your graveyard by sacrificing a land—which seamlessly feeds the land you just sacrificed directly into the trigger when Glacial Chasm enters the battlefield anew. Meanwhile, the *Forgotten Cellar* side of Walk-In Closet // Forgotten Cellar provides crucial redundancy by letting you play lands straight from your graveyard as well, ensuring your looping engine never misses a beat.
