Dualcaster Mage + Supernatural Stamina + Yahenni, Undying Partisan

Dualcaster Mage

Supernatural Stamina

Yahenni, Undying Partisan

How it works

1. Cast Supernatural Stamina by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Supernatural Stamina, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Supernatural Stamina.
5. Holding priority, activate Yahenni by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Yahenni abilities from step 5.

This elegant loop begins by targeting Dualcaster Mage with a copy of Supernatural Stamina generated by the Mage's own entrance trigger, creating a self-sustaining cycle of resurrection. Because Supernatural Stamina sets up a delayed return upon death, you can sacrifice the Mage to Yahenni, Undying Partisan's activation to instantly trigger that revival while simultaneously fueling Yahenni's growing power through its death-triggered counters. Every single time the Mage re-enters the battlefield, it triggers anew to copy Supernatural Stamina right back onto itself, letting you endlessly repeat the process for limitless sacrifices and trigger effects.
