Mortuary + Spore Frog + Gwenom, Remorseless + Cauldron of Essence

Mortuary

Spore Frog

Gwenom, Remorseless

Cauldron of Essence

How it works

1. Activate Spore Frog by sacrificing it.
2. When Spore Frog dies, Mortuary and Cauldron of Essence trigger.
3. Resolve the Mortuary trigger, putting Spore Frog from your graveyard onto the top of your library.
4. Resolve the Cauldron of Essence trigger, causing you to gain 1 life and each opponent to lose 1 life.
5. Resolve the Spore Frog ability.
6. Cast Spore Frog from the top of your library by paying 1 life.
7. Repeat.

This clever loop uses Mortuary to constantly intercept Spore Frog on its way to the graveyard, placing it right back on top of your library instead of letting it rest. Gwenom, Remorseless is the engine that lets you bypass traditional mana costs by letting you cast Spore Frog straight from the top of your library, paying life instead—a cost easily offset by the life drain and gain provided by Cauldron of Essence every time the frog dies and triggers its death effects. By repeatedly sacrificing Spore Frog to fog every combat phase, you create an unbreakable, self-sustaining cycle of life drain and protection.
