Mortuary + Viscera Seer + Vengeful Bloodwitch + Gwenom, Remorseless

Mortuary

Viscera Seer

Vengeful Bloodwitch

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing it.
2. When Viscera Seer dies, Mortuary and Vengeful Bloodwitch trigger.
3. Resolve the Mortuary trigger, putting Viscera Seer from your graveyard onto the top of your library.
4. Resolve the Vengeful Bloodwitch trigger, causing you to gain 1 life and target opponent to lose 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 clever loop turns a simple seer and a rotting vault into a relentless engine of attrition. As Viscera Seer is repeatedly sacrificed to its own ability, Mortuary ensures the card never truly rests, instantly placing it back on top of your library to be recast. Because Gwenom, Remorseless allows you to play cards from the top of your library by paying life instead of mana, you can easily afford the re-entry fee, especially with Vengeful Bloodwitch draining your opponent and padding your life total with every single death.
