Glacial Chasm + Mina and Denn, Wildborn + Crucible of Worlds

Glacial Chasm

Mina and Denn, Wildborn

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 ingenious defensive lock completely shuts down all damage dealt to you by leveraging Glacial Chasm's absolute protection while neatly sidestepping its mounting life payment and sacrifice drawbacks. By utilizing Crucible of Worlds, you can effortlessly replay the Chasm directly from your graveyard each turn after letting it go to its cumulative upkeep, ensuring you never have to actually pay its escalating life cost. Meanwhile, Mina and Denn, Wildborn provide the crucial extra land drop and a repeatable bounce effect, allowing you to easily manage the land you are forced to sacrifice when Glacial Chasm enters the battlefield.
