Rotlung Reanimator + Viscera Seer + Maskwood Nexus

Rotlung Reanimator

Viscera Seer

Maskwood Nexus

How it works

1. Activate Viscera Seer by sacrificing any other creature.
2. When the creature dies as a Cleric due to Maskwood Nexus, Rotlung Reanimator triggers, creating a 2/2 Zombie creature token.
3. Resolve the Viscera Seer ability.
4. Repeat.

The magic behind this engine lies in the clever synergy between Maskwood Nexus and Rotlung Reanimator, where the Nexus's passive ability turns every creature you control into every creature type—including a Cleric. This means that whenever you sacrifice a creature to Viscera Seer, Rotlung Reanimator sees a Cleric die and triggers to produce a 2/2 Zombie token. Because that Zombie is also instantly bestowed every creature type by Maskwood Nexus, you can immediately feed it back into Viscera Seer to repeat the loop indefinitely. This self-sustaining sacrifice loop lets you churn through your entire library with infinite scry triggers while generating an endless stream of death, entry, and exit events.
