Olivia's Attendants + Intruder Alarm + Brawl + March of the Machines

Olivia's Attendants

Intruder Alarm

Brawl

March of the Machines

How it works

1. Cast Brawl by paying 3.
2. Give Olivia's Attendants indestructible, if needed.
3. Activate Olivia's Attendants by tapping it, dealing damage equal to its power to itself.
4. Olivia's Attendants triggers, creating that many Blood artifact tokens.
5. The Bloods enter the battlefield as 0/0 creatures due to March of the Machines and die as a state-based action due to having 0 toughness.
6. Intruder Alarm triggers that many times, untapping all creatures.
7. Repeat from step 3.

This clever loop transforms self-inflicted damage into an endless cycle of creation and destruction, turning Olivia's Attendants into a self-contained cannon. By casting Brawl, every creature gains the ability to ping targets for damage equal to its power, allowing the Attendants to target itself for fiery retribution. Thanks to March of the Machines, the Blood tokens created by the Attendants' damage enter the battlefield as 0/0 creatures and immediately perish, which in turn triggers Intruder Alarm to untap all creatures over and over again so the Attendants can tap to repeat the process.
