Mortuary + Viscera Seer + Proper Burial + Gwenom, Remorseless

Mortuary

Viscera Seer

Proper Burial

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing it.
2. When Viscera Seer dies, Mortuary and Proper Burial trigger.
3. Resolve the Mortuary trigger, putting Viscera Seer from your graveyard onto the top of your library.
4. Resolve the Proper Burial 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 engine turns a modest sacrifice outlet into a perpetual loop by turning your graveyard into an extension of your hand. When you sacrifice Viscera Seer to its own ability, Mortuary instantly catches it on the way to the graveyard and places it right back on top of your library. Meanwhile, Proper Burial capitalizes on the death by padding your life total, which directly fuels the alternative casting cost granted by Gwenom, Remorseless to replay the Seer from the top of your library for life instead of mana.
