Blight Mound + Altar of Dementia + Cult Conscript + Pitiless Plunderer

Blight Mound

Altar of Dementia

Cult Conscript

Pitiless Plunderer

How it works

1. Activate Altar of Dementia by sacrificing Cult Conscript.
2. When Cult Conscript dies, Pitiless Plunderer and Blight Mound trigger, creating a creature token and a Treasure token.
3. Resolve the Altar of Dementia ability.
4. Activate Altar of Dementia by sacrificing the creature token.
5. When the creature token dies, it and Pitiless Plunderer triggers, creating a Treasure token and causing you to gain 1 life.
6. Resolve the Altar of Dementia ability.
7. Activate the Treasures by tapping and sacrificing them, adding 1.
8. Activate Cult Conscript by paying 1, returning it from your graveyard to the battlefield.
9. Repeat.

This brilliant loop turns a humble skeleton into a relentless mill engine by recycling it through the graveyard for the exact cost of its own resurrection. Every time you sacrifice Cult Conscript to Altar of Dementia, Pitiless Plunderer and Blight Mound spring into action, replacing your fallen warrior with a fresh Treasure token and a Pest token to fuel the next sacrifice. The Pest token's built-in lifegain buffer keeps your health total safe, while Altar of Dementia steadily chips away at your opponents' libraries until they have nothing left.
