Emmara, Soul of the Accord + Intruder Alarm + Grand Architect + Painter's Servant

Emmara, Soul of the Accord

Intruder Alarm

Grand Architect

Painter's Servant

How it works

1. 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.
2. Emmara triggers, creating a 1/1 Soldier creature token.
3. When the Soldier enters the battlefield, Intruder Alarm triggers, untapping all creatures.
4. Repeat from step 2.

This ingenious engine turns a tap into a self-sustaining loop by using Grand Architect's ability to tap Emmara, Soul of the Accord for restricted colorless mana. That very tap triggers Emmara to produce a Soldier token, which instantly satisfies Intruder Alarm's global untap condition upon entry. Meanwhile, Painter's Servant quietly ensures color rules are rewritten across the board, supporting the architecture of the loop while Grand Architect sets the stage. Every iteration resets the board state completely fresh, generating infinite creature tokens and infinite colorless mana to fuel your artifact-heavy ambitions.
