Provenance

Where it came from

Intruder Alarm was released in 1998 as part of the Stronghold expansion for Magic: The Gathering. Designed by Wizards of the Coast during a period of rapid growth for the game, the set focused on themes of defensive fortification and tactical board control. The card was intended to reward players for flooding the battlefield with creature tokens, providing a unique triggered ability that untaps all creatures whenever a new one enters play.

The artwork was illustrated by rk post, a prominent artist whose distinct, often eerie style became a staple of late-90s Magic sets. His vision for the card utilized a muted color palette and unsettling imagery to evoke the tension of a security breach. Upon its release, the card was viewed primarily as a niche engine for casual play, though it has since gained significant appreciation in competitive formats for its ability to create infinite mana or creature-tapping loops.
