How it works
Activate Adarkar Valkyrie by tapping it, targeting another creature you control.
Activate Shilgengar by sacrificing the creature targeted in step 1.
When the creature dies, Adarkar Valkyrie triggers, returning the sacrificed creature to the battlefield.
When the creature enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Resolve the Shilgengar ability
Repeat.
This clever cycle turns your board into a perpetual engine by pairing Adarkar Valkyrie's targeted revival with Shilgengar, Sire of Famine's sacrifice outlet, letting you repeatedly feed a creature to churn out Blood tokens. Whenever that sacrificed creature returns to the battlefield, Intruder Alarm's static ability triggers and untaps all creatures, including Adarkar Valkyrie, resetting the entire loop so you can repeat it indefinitely.
