Shilgengar, Sire of Famine + Dualcaster Mage + Feign Death

Shilgengar, Sire of Famine

Dualcaster Mage

Feign Death

How it works

1. Cast Feign Death by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Feign Death, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Feign Death.
5. Holding priority, activate Shilgengar 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 Shilgengar abilities from step 5.

This loop relies on a clever stacking of triggers to endlessly recur your creatures, powered by Shilgengar, Sire of Famine turning every sacrifice into valuable Blood tokens. By casting Feign Death and responding with Dualcaster Mage, the Mage's entry trigger copies the spell to target itself, ensuring it can always bounce back from the graveyard when sacrificed. You then feed that same Dualcaster Mage to Shilgengar, Sire of Famine's sacrifice ability, triggering the death-and-return loop while generating a steady stream of Blood tokens.
