Mortuary + Viscera Seer + Serrated Scorpion + Gwenom, Remorseless

Mortuary

Viscera Seer

Serrated Scorpion

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing Serrated Scorpion.
2. When Serrated Scorpion dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Serrated Scorpion from your graveyard onto the top of your library.
4. Resolve the Serrated Scorpion trigger, causing you to gain 2 life and dealing 2 damage to each opponent.
5. Resolve the Viscera Seer ability.
6. Cast Serrated Scorpion from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This elegant little loop turns your graveyard into a revolving door by letting Mortuary intercept Serrated Scorpion the moment Viscera Seer sends it to the graveyard, neatly placing it back on top of your library. From there, Gwenom, Remorseless steps in to let you cast the Scorpion straight from the top of your library, trading a tiny fraction of your life total for its mana value instead of a traditional cost. Every iteration drains your opponents and pads your life total thanks to Serrated Scorpion's own death trigger, while Viscera Seer acts as the reliable sacrifice engine that keeps the entire cycle moving.
