Glacial Chasm + The Gitrog Monster + Ramunap Excavator

Glacial Chasm

The Gitrog Monster

Ramunap Excavator

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 and The Gitrog Monster's first ability trigger.
5. Resolve The Gitrog Monster trigger, sacrificing Glacial Chasm.
6. Resolve the Glacial Chasm trigger, choosing not to pay and doing nothing as Glacial Chasm is no longer on the battlefield.
7. Repeat.

This impenetrable defense locks down combat and damage entirely behind Glacial Chasm's absolute protection, while turning its harsh upkeep penalty into a resource engine. Normally, paying the cumulative upkeep or managing the land sacrifice for Glacial Chasm and The Gitrog Monster would quickly overwhelm your board. However, The Gitrog Monster converts every land sacrifice into a fresh card draw, and Ramunap Excavator steps in to let you continually replay that same sacrificed land straight from your graveyard. The result is a self-sustaining loop that completely shields you from harm turn after turn while keeping your hand full.
