Glacial Chasm + Ramunap Excavator + Oracle of Mul Daya

Glacial Chasm

Ramunap Excavator

Oracle of Mul Daya

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 brilliant survival engine locks opponents out of ever damaging you by weaponizing Glacial Chasm's sacrifice requirement. Normally, the Chasm's cumulative upkeep and self-sacrificing entry trigger would drain your resources, but Ramunap Excavator lets you continuously replay it directly from your graveyard. Meanwhile, Oracle of Mul Daya accelerates your mana drops and lets you play lands right off the top of your library to replace whatever land you had to sacrifice when Glacial Chasm entered the battlefield.
