Dementia Sliver

Dementia Sliver was released in 2006 as part of the Time Spiral expansion, a set centered on the theme of nostalgia and the manipulation of Magic: The Gathering’s past. As a member of the Sliver creature type—a race of hive-minded entities that share physical and magical abilities with one another—this card was designed to capitalize on the fan-favorite mechanics established in earlier sets like Tempest and Legions. The set was noted for bringing back retired mechanics and concepts, positioning the Slivers as a central, recurring threat throughout the game's history.

The artwork was provided by Una Fricker, who utilized a distinct, muted color palette and organic, unsettling forms to depict the creature's psychic nature. Her design emphasizes the grotesque, alien anatomy characteristic of the Sliver species, reinforcing their role as parasitic invaders. Upon its release, the card was received as a solid inclusion for Sliver-themed decks, appreciated primarily for its tactical utility in forcing opponents to discard cards, which fit well within the broader mechanical intent of the set to revisit and evolve established archetypes.
