Altar of Dementia + Dualcaster Mage + Prison Break

Altar of Dementia

Dualcaster Mage

Prison Break

How it works

1. Cast Prison Break either from your hand by paying 4 or from your graveyard for its mayhem cost by paying 3, targeting any applicable target.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Prison Break.
4. Holding priority, activate Altar of Dementia by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Prison Break, with the copy targeting Dualcaster Mage
6. Resolve the Prison Break copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop turns a modest reanimation spell into an unstoppable engine by leveraging Dualcaster Mage's ability to copy spells as it enters the battlefield. By targeting Prison Break with the Mage's copy trigger and sacrificing the Mage to Altar of Dementia in response, you set up a self-sustaining cycle where the spell continuously brings the Mage right back from the graveyard. Altar of Dementia uses this endless stream of sacrifices to mill your opponents' entire libraries into oblivion, turning a simple flash creature and a sorcery into a definitive win condition.
