Shilgengar, Sire of Famine + Dualcaster Mage + Faith's Reward

Shilgengar, Sire of Famine

Dualcaster Mage

Faith's Reward

How it works

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

This recursive loop hinges on the clever interaction between Dualcaster Mage and Faith's Reward, where casting the former in response to the latter allows the mage to copy the spell that brought it back. To fuel the engine, Shilgengar, Sire of Famine sits on the battlefield ready to sacrifice Dualcaster Mage for a Blood token, sending the Mage straight to the graveyard so that Faith's Reward can pull it right back alongside any other casualties. By endlessly repeating this sacrifice and resurrection cycle, you generate infinite death triggers, enter-the-battlefield triggers, and an unbounded horde of Blood tokens.
