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.
Holding priority, cast Dualcaster Mage by paying its mana cost.
When Dualcaster Mage enters, it triggers, targeting Prison Break.
Holding priority, activate Woe Strider by sacrificing Dualcaster Mage.
Resolve the Dualcaster Mage trigger, copying Prison Break, with the copy targeting Dualcaster Mage
Resolve the Prison Break copy, returning Dualcaster Mage from your graveyard to the battlefield.
Repeat from step 3.
This clever loop transforms Prison Break into a recursive engine by leveraging Dualcaster Mage's clever flash entry to constantly copy the spell that keeps bringing it back. As Dualcaster Mage flashes in to duplicate the original reanimation spell, Woe Strider stands ready to quietly sacrifice the Mage, sending it right back to the graveyard just in time for the copy to snatch it back onto the battlefield. Woe Strider's presence doesn't just enable the sacrifice loop—its passive scry ability turns every iteration into infinite deck manipulation, letting you sculpt your draws while generating an endless storm of death and entry triggers.
