Mortuary + Ashes of the Abhorrent + Viscera Seer + Gwenom, Remorseless

Mortuary

Ashes of the Abhorrent

Viscera Seer

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing it.
2. When Viscera Seer dies, Mortuary and Ashes of the Abhorrent trigger.
3. Resolve the Mortuary trigger, putting Viscera Seer from your graveyard onto the top of your library.
4. Resolve the Ashes of the Abhorrent 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 clever loop hinges on Mortuary's ability to seamlessly recycle any creature that hits the graveyard directly back onto the top of your library. By sacrificing Viscera Seer to its own activation, you trigger that recursion alongside Ashes of the Abhorrent, which conveniently buffers your life total with every death so you can afford the alternate casting costs. Gwenom, Remorseless provides the critical engine that allows you to cast that creature straight off the top of your library without spending mana. Instead of paying mana, Gwenom's static-like replacement effect lets you pay life equal to the creature's mana value, fueling an endless cycle of sacrifices, scrys, and lifegain.
