Audacious Reshapers + Mortuary + Intruder Alarm + Peace Strider

Audacious Reshapers

Mortuary

Intruder Alarm

Peace Strider

How it works

1. Activate Audacious Reshapers by tapping it and sacrificing Peace Strider.
2. When Peace Strider dies, Mortuary triggers, putting Peace Strider on top of your library from your graveyard.
3. Resolve the Audacious Reshapers ability, revealing Peace Strider from the top of your library, then putting it onto the battlefield and dealing 1 damage to you.
4. When Peace Strider enters the battlefield, it and Intruder Alarm trigger.
5. Resolve the Intruder Alarm trigger, untapping all creatures.
6. Resolve the Peace Strider trigger, causing you to gain 3 life.
7. Repeat.

This ingenious loop relies on Mortuary to intercept your creatures as they hit the graveyard, immediately stacking them back on top of your library so Audacious Reshapers can pull them right out again. As Peace Strider cycles endlessly between the battlefield and the library, its entry triggers a wave of life gain while simultaneously waking up Intruder Alarm to untap Audacious Reshapers for the next iteration. Because the life gained outpaces the damage dealt by the Reshapers' search, you achieve an unstoppable, self-sustaining cycle that generates infinite resources.
