Umbral Collar Zealot + Felidar Guardian + Angel of Indemnity

Umbral Collar Zealot

Felidar Guardian

Angel of Indemnity

How it works

1. Cast Felidar Guardian by paying its mana cost.
2. When Felidar Guardian enters the battlefield, it triggers, targeting Angel of Indemnity.
3. Holding priority, activate Umbral Collar Zealot by sacrificing Felidar Guardian.
4. Resolve the Felidar Guardian ability, blinking Angel of Indemnity.
5. When Angel of Indemnity enters the battlefield, it triggers, returning Felidar Guardian from your graveyard to the battlefield.
6. Repeat from step 2.

This clever loop achieves infinity by establishing a perpetual cycle of rescue and resurrection between your top-end threat and its smaller enablers. When Felidar Guardian enters the battlefield, its blink ability targets Angel of Indemnity to reset its graveyard-retrieval trigger, while Umbral Collar Zealot stands ready to sacrifice the Guardian in response and feed your engine with continuous surveil triggers. As the Angel blinks back in, its entry effect pulls Felidar Guardian straight out of your graveyard to restart the whole sequence.
