Ashnod's Altar + Dualcaster Mage + Vincent's Limit Break

Ashnod's Altar

Dualcaster Mage

Vincent's Limit Break

How it works

1. Cast Vincent's Limit Break by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Vincent's Limit Break, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Vincent's Limit Break.
5. Holding priority, activate Ashnod's Altar by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
