Viscera Seer + Moment of Reckoning + Dualcaster Mage

Viscera Seer

Moment of Reckoning

Dualcaster Mage

How it works

1. Cast Moment of Reckoning by paying its mana cost
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Moment of Reckoning.
4. Holding priority, activate Viscera Seer by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Moment of Reckoning
6. Resolve the Moment of Reckoning copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This delightful loop uses Dualcaster Mage to perpetually recur itself while tearing apart the opponent's board. By choosing modes on Moment of Reckoning to both destroy a nonland permanent and return Dualcaster Mage from your graveyard to the battlefield, you can keep the chain going indefinitely. Viscera Seer acts as the necessary sacrifice outlet to send Dualcaster Mage back to the graveyard each iteration, while also letting you filter your deck with infinite scrys along the way.
