Ashnod's Altar + Dualcaster Mage + Prison Break

Ashnod's Altar

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 Ashnod's Altar 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 delightful loop transforms a simple recursion spell into an endless engine of sacrifice and resurrection. By casting Prison Break and holding priority to drop Dualcaster Mage, the Mage's enter-the-battlefield trigger targets the original sorcery on the stack. Before that copy resolves, Ashnod's Altar converts the Mage into a pair of colorless mana to fund future casts, sending the wizard safely to the graveyard. The resolved copy of Prison Break then plucks Dualcaster Mage right back onto the battlefield, letting you repeat the entire process to generate an endless cascade of sacrifice triggers and infinite colorless mana.
