Mortuary + Moldervine Reclamation + Viscera Seer + Gwenom, Remorseless

Mortuary

Moldervine Reclamation

Viscera Seer

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing it.
2. When Viscera Seer dies, Mortuary and Moldervine Reclamation trigger.
3. Resolve the Mortuary trigger, putting Viscera Seer from your graveyard onto the top of your library.
4. Resolve the Moldervine Reclamation trigger, causing you to gain 1 life and draw a card.
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 turns a sacrifice outlet into a self-sustaining engine by taking advantage of replacement and top-deck manipulation. When you sacrifice Viscera Seer to its own ability, Mortuary immediately intercepts it to tuck it safely back onto the top of your library, while Moldervine Reclamation rewards the creature's death with a life and a drawn card. Meanwhile, Gwenom, Remorseless is the linchpin that allows you to bypass mana costs entirely, letting you cast the Seer right back off the top of your library for a mere 1 life. Because the life you pay is easily offset by the life gained, you can cycle this sequence endlessly to churn through your deck and rack up an enormous storm count.
