Afterlife from the Loam

Spawning Pit

How it works

1. Cast Afterlife from the Loam by paying at most 5.
2. Holding priority, cast Dualcaster Mage by paying 1.
3. When Dualcaster Mage enters the battlefield, it triggers, targeting Afterlife from the Loam.
4. Holding priority, activate Spawning Pit by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Afterlife from the Loam, targeting Dualcaster Mage and any other creature(s) as desired.
6. Resolve the copy of Afterlife from the Loam, returning the targeted creatures from your graveyard to the battlefield.
7. Repeat from step 3.
