Emmara, Soul of the Accord + Intruder Alarm + Grand Architect + Cerulean Wisps

Emmara, Soul of the Accord

Intruder Alarm

Grand Architect

Cerulean Wisps

How it works

1. Cast Cerulean Wisps by paying , causing Emmara to become blue until end of turn and causing you to draw a card.
2. Activate Grand Architect's second ability by tapping Emmara, adding CC that can only be spent to cast artifact spells and/or to activate abilities of artifacts.
3. Emmara triggers, creating a 1/1 Soldier creature token.
4. When the Soldier enters the battlefield, Intruder Alarm triggers, untapping all creatures.
5. Repeat from step 2.

This clever loop turns a simple tap into a cascade of relentless activity, anchored by Grand Architect's ability to squeeze two colorless mana out of any blue creature at the cost of tapping it. By using Cerulean Wisps to paint Emmara, Soul of the Accord blue, she becomes a valid target to be tapped for Grand Architect's mana generation. That very tap immediately triggers Emmara, Soul of the Accord to spawn a 1/1 Soldier token with lifelink, which in turn wakes up Intruder Alarm to untap your entire board. Because Intruder Alarm resets everything whenever a creature enters the battlefield, you can endlessly repeat the process, feeding the mana into your artifacts while generating an infinite army of soldiers.
