Glacial Chasm + Ramunap Excavator + Druid Class

Glacial Chasm

Ramunap Excavator

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 resilient defensive lock revolves around constantly cycling Glacial Chasm to bypass its punishing cumulative upkeep, letting you completely blank all damage dealt to you while keeping your attackers safely tucked away. Ramunap Excavator acts as the engine's core by letting you replay the sacrificed land directly from your graveyard, ensuring you always have a fresh sacrifice ready when Glacial Chasm enters the battlefield anew. Meanwhile, Druid Class provides essential support by padding your life total through its landfall trigger every time a land returns, helping offset any life losses along the way.
