Dr. Madison Li + Intruder Alarm + Robobrain War Mind + Ravenous Intruder

Dr. Madison Li

Intruder Alarm

Robobrain War Mind

Ravenous Intruder

How it works

1. Cast Robobrain War Mind by paying 3.
2. When Robobrain War Mind enters, it 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 Intruder Alarm trigger, untapping all creatures.
5. Activate Ravenous Intruder by sacrificing Robobrain War Mind.
6. Activate Dr. Madison Li by tapping it and paying EEEEE, returning Robobrain War Mind from your graveyard to the battlefield.
7. Repeat from step 2.

This engine turns the recycling loop of Dr. Madison Li and Ravenous Intruder into a self-sustaining cycle by looping Robobrain War Mind's entry into the battlefield. Every time Robobrain War Mind returns, Intruder Alarm triggers to untap your entire board—crucially allowing Dr. Madison Li to untap and ready her five-energy graveyard recursion ability—while simultaneously providing the energy needed to fuel it, assuming you have enough artifact creatures to support the cost. Meanwhile, Ravenous Intruder stands ready to sacrifice Robobrain War Mind to send it back to the graveyard, letting you repeat the cycle indefinitely for infinite triggers and a massive creature.
