Glacial Chasm + Conduit of Worlds + Druid Class

Glacial Chasm

Conduit of Worlds

Druid Class

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 lock completely shields you behind Glacial Chasm's damage prevention while sidestepping its painful upkeep costs and sacrifice requirement. By utilizing Conduit of Worlds, you can continuously replay the Chasm from your graveyard turn after turn, letting you effortlessly sacrifice it to its own cumulative upkeep and bypass paying life as age counters pile up. Meanwhile, Druid Class provides the crucial extra land drop and life gain to offset any lingering costs, while its Level 3 ability can even turn your recurring lands into a lethal attacking force once your opponents are entirely locked out of harming you.
