Glacial Chasm + Mina and Denn, Wildborn + Ramunap Excavator

Glacial Chasm

Mina and Denn, Wildborn

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 triggers, allowing you to choose not to pay the cost and sacrifice it instead.
5. Repeat.

By combining Ramunap Excavator with Mina and Denn, Wildborn, you gain the ability to effortlessly loop land drops straight from your graveyard while bypassing the usual limits on your turn. This constant recycling of real estate allows you to repeatedly drop and sacrifice Glacial Chasm, entirely dodging its harsh cumulative upkeep costs and land-sacrifice triggers. Because Glacial Chasm's entry prevents all damage dealt to you, you effectively lock your opponents out of ever hurting you while keeping your battlefield safe to set up the rest of your game plan.
