Shilgengar, Sire of Famine + Infuse with Vitality + Dualcaster Mage

Shilgengar, Sire of Famine

Infuse with Vitality

Dualcaster Mage

How it works

1. Cast Infuse with Vitality by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Infuse with Vitality, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Infuse with Vitality.
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 crafty loop spins out infinite resources by trapping Dualcaster Mage in an endless cycle of self-preservation and resurrection. You start by casting Infuse with Vitality and letting Dualcaster Mage copy it upon entry, targeting the Mage itself so it's guaranteed to return upon dying. From there, Shilgengar, Sire of Famine steps in as the grand orchestrator, letting you continually sacrifice the Mage to fuel its ability while the Infuse with Vitality trigger immediately brings the Mage right back to do it all over again.
