Bhaal, Lord of Murder + Shilgengar, Sire of Famine

Bhaal, Lord of Murder

Shilgengar, Sire of Famine

How it works

1. Activate Shilgengar by sacrificing a persist creature that does not have a -1/-1 counter on it.
2. When the creature dies, its persist ability and Bhaal trigger.
3. Resolve the Bhaal trigger, putting a +1/+1 counter on the remaining persist creature.
4. Resolve the sacrificed creature's persist trigger, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. Resolve the Shilgengar ability from step 1.
6. Repeat.
