Glacial Chasm + Aesi, Tyrant of Gyre Strait + Crucible of Worlds

Glacial Chasm

Aesi, Tyrant of Gyre Strait

Crucible of Worlds

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 lockdown loop lets you completely ignore Glacial Chasm's brutal life-draining cumulative upkeep by simply letting the land sacrifice itself, only to immediately replay it from your graveyard thanks to Crucible of Worlds. While Glacial Chasm's enter-the-battlefield trigger forces you to sacrifice a land every time it reappears, Aesi, Tyrant of Gyre Strait smoothly offsets this cost by drawing you extra cards whenever that land drops. The result is a total damage immunity shield that traps opponents behind an unyielding defensive wall without ever draining your own life total dry.
