Intruder Alarm + Flamewright

Intruder Alarm

Flamewright

How it works

1. Pay 1 and tap Flamewright to create a 1/1 Construct.
2. The Construct enters untapping all creatures you control.
3. Repeat.

This loop is a masterclass in turning a trickle of mana into a raging storm, fueled entirely by the clever geometry of Intruder Alarm. As Flamewright taps to churn out a 1/1 Construct artifact creature token with defender, Intruder Alarm's static ability triggers off that new arrival and immediately untaps Flamewright, readying it to repeat the process. Because every single iteration untaps your entire board, you can weave in any other mana-producing creatures you control to generate infinite mana alongside your infinite army of Constructs.
