How it works
Cast Robobrain War Mind by paying 3.
When Robobrain War Mind enters, it and Intruder Alarm trigger.
Resolve the Robobrain War Mind trigger, causing you to get E for each artifact creature you control.
Resolve the Intruder Alarm trigger, untapping all creatures.
Activate Krark-Clan Grunt by sacrificing Robobrain War Mind.
Activate Dr. Madison Li by tapping it and paying EEEEE, returning Robobrain War Mind from your graveyard to the battlefield.
Repeat from step 2.
This clever loop puts Intruder Alarm's global untap trigger to work every single time Robobrain War Mind enters the battlefield, immediately refreshing Dr. Madison Li and any other creatures you control. You feed the machinery by using Krark-Clan Grunt to sacrifice Robobrain War Mind, sending it straight to the graveyard so Dr. Madison Li's hefty five-energy ability can haul it right back onto the battlefield. Because Dr. Madison Li also fuels your energy reserves whenever you cast an artifact spell, you can easily sustain this cyclical resurrection while keeping your entire board perpetually untapped and ready for action.
