Rotlung Reanimator + Altar of Dementia + Maskwood Nexus

Rotlung Reanimator

Altar of Dementia

Maskwood Nexus

How it works

1. Activate Altar of Dementia 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 Altar of Dementia ability.
4. Repeat.

The true genius of this combination lies in Maskwood Nexus, whose passive blanket effect transforms every creature you own into every creature type simultaneously—meaning the Zombie token you sacrifice is also treated as a Cleric. That crucial type-matching allows Rotlung Reanimator's triggered ability to fire off every single time a creature bites the dust, constantly replacing your fallen units with fresh fresh recruits. You then feed those newly spawned tokens right back into Altar of Dementia to mill away your opponent's entire library through an endless loop of sacrifice and resurrection.
