Dr. Madison Li + Intruder Alarm + Robobrain War Mind + Grinding Station

Dr. Madison Li

Intruder Alarm

Robobrain War Mind

Grinding Station

How it works

1. Cast Robobrain War Mind by paying 3.
2. When Robobrain War Mind enters, it, Grinding Station and Intruder Alarm trigger.
3. Resolve the Robobrain War Mind trigger, causing you to get E for each artifact creature you control.
4. Resolve the Grinding Station trigger, untapping it.
5. Resolve the Intruder Alarm trigger, untapping all creatures.
6. Activate Grinding Station by tapping it and sacrificing Robobrain War Mind.
7. Activate Dr. Madison Li by tapping it and paying EEEEE, returning Robobrain War Mind from your graveyard to the battlefield.
8. Repeat from step 2.

This brilliant loop centers around Intruder Alarm, which ensures that every time Robobrain War Mind enters the battlefield, its creature arrival triggers a total untap of all your creatures. That untap readiness fuels Grinding Station, allowing you to sacrifice Robobrain War Mind to mill an opponent while Grinding Station immediately untaps itself thanks to the incoming artifact. Meanwhile, Dr. Madison Li's hefty energy-paying activated ability steps in to fish Robobrain War Mind right back out of the graveyard and onto the battlefield tapped, an action that is continuously supported by the energy counters generated by Dr. Madison Li's own artifact-casting triggers and Robobrain War Mind's entering-the-battlefield energy bonus.
