Umbral Collar Zealot + Reluctant Role Model

Umbral Collar Zealot

Reluctant Role Model

How it works

1. Activate Umbral Collar Zealot by sacrificing the persist creature that has a +1/+1 counter on it.
2. When that creature dies, its persist ability and Reluctant Role Model trigger.
3. Resolve Reluctant Role Model's ability, putting at least two +1/+1 counters onto the surviving persist creature due to the counter-increasing effect.
4. If that creature had a -1/-1 counter on it, remove that and one of the +1/+1 counters from it as a state-based action.
5. Resolve the persist ability from step 2, returning the persist creature from your graveyard to the battlefield with a -1/-1 counter.
6. Resolve the Umbral Collar Zealot ability from step 1.
7. Repeat.
