Mortuary + Viscera Seer + Panicked Bystander // Cackling Culprit + Gwenom, Remorseless

Mortuary

Viscera Seer

Panicked Bystander // Cackling Culprit

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing it.
2. When Viscera Seer dies, Mortuary and Panicked Bystander // Cackling Culprit trigger.
3. Resolve the Mortuary trigger, putting Viscera Seer from your graveyard onto the top of your library.
4. Resolve the Panicked Bystander // Cackling Culprit trigger, causing you to gain 1 life
5. Resolve the Viscera Seer ability.
6. Cast Viscera Seer from the top of your library by paying 1 life.
7. Repeat.

This ingenious loop relies on Mortuary to intercept your creatures as they hit the graveyard, immediately recycling them right back to the top of your library. Viscera Seer acts as the engine by providing a free sacrifice outlet while its own death triggers the whole sequence. Meanwhile, Gwenom, Remorseless enables you to cast that freshly recycled creature straight from the top of your library by paying life instead of mana, turning Mortuary's placement into a continuous reload. As you churn through this cycle, Panicked Bystander // Cackling Culprit banks the life you need to pay Gwenom's alternative casting cost, generating an endless stream of death, sacrifice, and lifegain triggers.
