Dr. Madison Li + Decoction Module + Intruder Alarm + Myr Battlesphere + Altar of Dementia

Dr. Madison Li

Decoction Module

Intruder Alarm

Myr Battlesphere

Altar of Dementia

How it works

1. Activate Dr Madison Li's third ability by tapping it and paying EEEEE, returning Myr Battlesphere from your graveyard to the battlefield.
2. When Myr Battlepshere enters the battlefield, it, Intruder Alarm and Decoction Module triggers.
3. Resolve the Intruder Alarm trigger, untapping all creatures.
4. Resolve the Decoction Module trigger, causing you to get E.
5. Resolve the Myr Battlesphere trigger, creating four 1/1 Myr artifact creature tokens.
6. When the Myrs enter the battlefield, Intruder Alarm and Decoction Module trigger four times.
7. Resolve all Intruder Alarm triggers, untapping all creatures.
8. Resolve all Decoction Module triggers, causing you to get EEEE.
9. Activate Altar of Dementia by sacrificing Myr Battlesphere, causing target player to mill cards equal to Myr Battlesphere's power.
10. Repeat.

This intricate loop turns the mechanical synchronization of artifact tokens and energy into an endless engine of destruction. As Myr Battlesphere repeatedly enters the battlefield, it floods the board with four Myr artifact creature tokens—each one immediately triggering Decoction Module for a steady stream of energy and causing Intruder Alarm to forcefully untap your entire board, keeping Dr. Madison Li fresh and ready to act. Meanwhile, Dr. Madison Li's ability spends that accumulated energy to drag Myr Battlesphere right back out of your graveyard whenever it falls, fueling a continuous cycle where Altar of Dementia can endlessly sacrifice the Battlesphere to mill out any opponent.
