Felidar Guardian + Reveillark + Umbral Collar Zealot

Felidar Guardian

Reveillark

Umbral Collar Zealot

How it works

1. Cast Felidar Guardian by paying 3.
2. When Felidar Guardian enters the battlefield, it triggers, targeting Reveillark.
3. Holding priority, activate Umbral Collar Zealot by sacrificing Felidar Guardian.
4. Resolve the Felidar Guardian trigger, blinking Reveillark.
5. When Reveillark leaves the battlefield, it triggers, returning Felidar Guardian and up to one other creature with power 2 or less from your graveyard to the battlefield.
6. Repeat from step 2.

This ingenious loop turns a simple blink into an infinite engine of life and death, utilizing Felidar Guardian's entry trigger to exile and reset Reveillark repeatedly. As Reveillark leaves the battlefield, its delayed trigger steps in to pull the cat right back alongside any other small creature, fueling Umbral Collar Zealot's sacrifice outlet. By feeding Felidar Guardian to Umbral Collar Zealot in response to its own entry trigger, you bypass timing restrictions to instantly trigger Reveillark's leave-the-battlefield ability, allowing you to cycle through your deck with infinite surveil triggers while continuously recurring your entire low-power graveyard.
