Mortuary + Omarthis, Ghostfire Initiate + Gwenom, Remorseless

Mortuary

Omarthis, Ghostfire Initiate

Gwenom, Remorseless

How it works

1. Cast Omarthis either from your hand by paying 0 or from the top of your library by paying 0 life.
2. Omarthis enters and dies as a state-based action due to having 0 toughness.
3. Mortuary triggers, putting Omarthis from your graveyard onto the top of your library.
4. Repeat.

This clever loop turns the inherent fragility of a zero-toughness Omarthis, Ghostfire Initiate into an engine of endless repetition, fueled seamlessly by Mortuary to constantly cycle the elemental back to the top of your library. From there, Gwenom, Remorseless steps in as the mastermind, allowing you to bypass mana costs entirely and cast Omarthis straight off the top of your library by paying life instead—a cost entirely negated by Gwenom's own lifelink when needed. As Omarthis repeatedly enters, dies, and returns, you effortlessly amass infinite storm count, creature leaves-the-battlefield triggers, and death triggers to overwhelm your opponents.
