Whir of Invention (PAER-49p) is a Rare Instant from the Aether Revolt Promos set. It has Improvise and lets you search your library for an artifact card with mana value X or less and put that card onto the battlefield. Because it can cheat artifacts directly into play, it sees use in artifact-focused blue decks and toolbox strategies.
