Quartet by Mark Mason

Give your audience a visual mystery they can follow from the first guess to the final impossible moment. In Quartet, Mark Mason’s red- and blue-backed cards repeatedly change places while remaining in view, building to a finale where both cards are shown in separate hands.

• Clear colors: A red-backed card and a blue-backed card make each change easy for spectators to track.
• Audience participation: Invite someone to guess which hand holds each card before the visual surprises begin.
• Escalating sequence: The cards change places several times, including a final change while both are visible.
• Two-card set: The effect uses only two cards, with no flaps or magnets.
• Ready for another performance: Unfold the cards, show their fronts and backs, and return them to the wallet; the trick is reset.

Quartet gives you a focused card routine with a strong visual finish. The repeated changes let you build anticipation before revealing the cards from every side.
