Glacial Chasm + Mina and Denn, Wildborn + Conduit of Worlds

Glacial Chasm

Mina and Denn, Wildborn

Conduit of Worlds

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 lock completely shuts down all damage directed at you by exploiting Glacial Chasm's self-sacrificing cumulative upkeep and its enter-the-battlefield land sacrifice, allowing you to bypass its life-payment drawbacks entirely. Mina and Denn, Wildborn provide the extra land drop needed to replay the Chasm turn after turn, while also fueling a backup bounce if necessary. Finally, Conduit of Worlds lets you seamlessly replay Glacial Chasm directly out of your graveyard once it hits the bin, creating an impenetrable defensive loop that keeps you safe from harm indefinitely.
