2. When the persist creature dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When the persist creature enters, Surrak and Goreclaw triggers, putting a +1/+1 counter on the persist creature.
4. Resolve the Umbral Collar Zealot ability.
5. Repeat
