Provenance

Where it came from

Thinking Cap was released in 2024 as part of the Murders at Karlov Manor expansion for Magic: The Gathering. Set on the plane of Ravnica, this artifact card was designed to reflect the set's central theme of investigation and mystery-solving, fitting into the equipment sub-type that emphasizes the mechanical focus on draw-smoothing and equipment synergy common in limited play environments.

The card was illustrated by Tony Foti, a prolific artist for the franchise known for his clean, illustrative style. Foti’s design depicts an intricate, clockwork-inspired headpiece that evokes the high-fantasy steampunk aesthetic of the Ravnica plane. While it is a common-rarity card intended for deck building, it is frequently cited by collectors for its clear, functional artwork that captures the essence of the 'detective' archetype prevalent throughout the set.
