Dr. Madison Li + Decoction Module + Intruder Alarm + Myr Battlesphere + Krark-Clan Ironworks

Dr. Madison Li

Decoction Module

Intruder Alarm

Myr Battlesphere

Krark-Clan Ironworks

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 Krark-Clan Ironworks by sacrificing Myr Battlesphere, adding CC.
10. Repeat.

This intricate loop relies on looping Myr Battlesphere's entry triggers to continuously flood the board with Myrs, fueling both infinite artifact sacrifices and massive energy gains. Decoction Module and Dr. Madison Li work in tandem to convert those incoming creatures and cast artifacts into a steady stream of energy, which Dr. Madison Li then spends to recur Myr Battlesphere straight from the graveyard. Meanwhile, Intruder Alarm acts as the vital untap engine that resets your entire board—including Dr. Madison Li and Krark-Clan Ironworks—every single time a token or the Battlesphere arrives, letting you feed the Ironworks for infinite colorless mana and repeat the cycle indefinitely.
