Glacial Chasm + Perennial Behemoth + Song of Creation

Glacial Chasm

Perennial Behemoth

Song of Creation

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 fascinating defensive lock centers around cycling Glacial Chasm in and out of play to completely blank all incoming damage without ever paying its punishing cumulative upkeep cost. Perennial Behemoth acts as your engine's anchor, allowing you to continually play that sacrificed land right back from your graveyard. Meanwhile, Song of Creation accelerates your entire strategy by granting you an additional land drop each turn and drawing you two cards whenever you cast a spell, keeping your hand fully stocked with the resources you need to sustain the loop.
