Intruder Alarm Price

Updated 2026-07-28

Intruder Alarm from 8th Edition has registered a price move in the available windows where the 7-day and 30-day gains are identical, indicating the entire shift occurred within the past week and the 30-day measurement captured it fully. This pattern is characteristic of a speculator buyout or a single large buyer clearing visible inventory and resetting the market price. Intruder Alarm is a well-documented combo enabler in Commander: it untaps all creatures whenever a creature enters the battlefield, creating the foundation for infinite mana or loop combinations in decks built around creature-based activations. 8th Edition is out of print, and the card has not received a core-set reprint since, leaving supply genuinely constrained. Whether the current price holds depends on how much inventory remained outside the initial repricing. When supply reasserts itself after a buyout event, a corrective wave of copies typically compresses gains within weeks.
