Audacious Reshapers + Mortuary + Intruder Alarm + Enatu Golem

Audacious Reshapers

Mortuary

Intruder Alarm

Enatu Golem

How it works

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

This clever loop centers on the recursive manipulation of a single artifact creature, using Audacious Reshapers to repeatedly sacrifice Enatu Golem and instantly pull it right back from the library. While the Reshapers take a minor toll by dealing damage, Mortuary ensures Enatu Golem goes straight back to the top of your library instead of staying in the graveyard, completely bypassing normal deck attrition. Meanwhile, Intruder Alarm acts as the vital untap engine, responding to the Golem's reentry with a global untap that refreshes Audacious Reshapers for the next iteration. As an added bonus, Enatu Golem's own death trigger offsets the self-inflicted damage by continuously padding your life total, letting you safely spin this engine infinitely.
