Tortured Existence + Pitiless Plunderer + Altar of Dementia + Quintorius, History Chaser

Tortured Existence

Pitiless Plunderer

Altar of Dementia

Quintorius, History Chaser

How it works

1. Activate Tortured Existence by paying and discarding a creature card, returning another creature card from your graveyard to your hand.
2. Quintorius, History Chaser triggers, creating a creature token.
3. Activate Altar of Dementia by sacrificing the creature token.
4. When the creature token dies, Pitiless Plunderer triggers, creating a Treasure token.
5. Resolve the Altar of Dementia ability.
6. Activate a Treasure by tapping and sacrificing it, adding .
7. Repeat.

This clever loop turns graveyard recycling into an engine of infinite mill by weaving together four distinct permanents. At the heart of the engine, Tortured Existence acts as a recursive valve by swapping creatures between your hand and graveyard, which in turn causes Quintorius, History Chaser to flood the board with Spirit tokens every time a card leaves your yard. Each of those generated tokens is immediately fed into Altar of Dementia to chew through your opponent's library, while Pitiless Plunderer quietly watches the carnage to generate the black mana needed via Treasure tokens to keep paying for Tortured Existence over and over again.
