Audacious Reshapers + Mortuary + Intruder Alarm + Onulet

Audacious Reshapers

Mortuary

Intruder Alarm

Onulet

How it works

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

This clever loop turns a simple artifact sacrifice into a perpetual motion machine by weaponizing the graveyard and the top of your library. When you activate Audacious Reshapers, you sacrifice Onulet to instantly dig it back out of your library, cushioned by the life-gain buffer of Onulet's own death trigger. Meanwhile, Mortuary ensures Onulet never truly stays in the graveyard, neatly placing it right back on top of your library to be found again. Finally, Intruder Alarm acts as the mechanical heartbeat of the operation, using Onulet's repeated entry to untap Audacious Reshapers so you can repeat the process indefinitely.
