Intruder Alarm + Tocatli Honor Guard

Intruder Alarm

Tocatli Honor Guard

How it works

1. Intruder Alarm's first ability prevents creatures from untapping during their controller's untap step.
2. Because Tocatli Honor Guard prevents abilities from triggering whenever a creature enters the battlefield, Intruder Alarm's second ability does not trigger to untap them.

This fascinating little lockdown relies on the quiet presence of Tocatli Honor Guard to fundamentally alter how the battlefield behaves. While Intruder Alarm normally turns every creature's entry into a chaotic frenzy of untapping, the Honor Guard steps in to suppress those creature-entry triggers entirely. Without those triggers firing, the global restriction from Intruder Alarm takes full effect, freezing your opponents' forces in place and locking down their board completely.
