Activate Umbral Collar Zealot by sacrificing a creature token.
When the creature dies, Eloise's first and second abilities trigger, causing you to create a Clue token and then to surveil 1.
Matoya triggers, causing you to draw a card.
The Locust God triggers, creating a 1/1 Insect creature token with flying and haste.
Resolve the Umbral Collar Zealot ability.
Repeat.
This clever loop transforms a simple sacrifice into a self-sustaining engine of discovery and creation. It all starts when Umbral Collar Zealot sacrifices a creature token, which immediately triggers Eloise, Nephalia Sleuth to both investigate—leaving behind a Clue—and surveil 1. That surveil action satisfies the condition for Matoya, Archon Elder to have you draw a card, which in turn prompts The Locust God to churn out a fresh 1/1 Insect token ready to feed back into the Zealot.
