Dr. Madison Li + Intruder Alarm + Robobrain War Mind + Ashnod's Altar

Dr. Madison Li

Intruder Alarm

Robobrain War Mind

Ashnod's Altar

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 Ashnod's Altar 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 ingenious engine relies on a clever loop of sacrifice and reanimation to continuously trigger arrival effects. When Robobrain War Mind enters the battlefield, Intruder Alarm triggers to untap all creatures, ensuring Dr. Madison Li is fresh and ready for action. You then feed Robobrain War Mind to Ashnod's Altar to generate colorless mana, putting the creature right into the graveyard. Finally, you cash in the energy accumulated by Dr. Madison Li's first ability (or fueled by your artifact creature count) to pay the heavy activation cost of Dr. Madison Li's fifth ability, pulling Robobrain War Mind straight back to the battlefield to restart the cycle.
