Screams from Within + Altar of Dementia + Quintorius, History Chaser

Screams from Within

Altar of Dementia

Quintorius, History Chaser

How it works

1. Activate Altar of Dementia by sacrificing the creature that has Screams from Within attached.
2. When the creature dies, Screams from Within triggers, returning it from your graveyard to the battlefield attached to another creature you control.
3. Quintorius, History Chaser triggers, creating a creature token.
4. Resolve the Altar of Dementia ability.
5. Repeat.

This gruesome loop hinges on the recursive nature of Screams from Within, which automatically returns to the battlefield from your graveyard every time the creature it enchants perishes. By using Altar of Dementia to sacrifice that unfortunate soul, you instantly mill cards while setting up the enchantment's mandatory return to latch onto a fresh target. Meanwhile, Quintorius, History Chaser watches over this morbid cycle, triggering its ability every single time Screams from Within leaves your graveyard to continuously churn out 3/2 Spirit tokens.
