Magician and professional puzzle-solver Chris Ramsay revealed a very special promotional video: a real-life Bronze Chest built as a very elaborate puzzle box. If you're not familiar with the genre: puzzle boxes have been enjoying a bit of a renaissance in recent years. In addition to the incredible woodworking usually associated with the modern puzzle boxes, electronics were incorporated into this chest to give it light and sound effects as well as some very clever tie-ins to both the lore and mechanics of Legends of Runeterra.

Even if puzzle boxes aren't normally your thing, we can highly recommend this video to any fans of CCGs -- the amount of detail and theme that went into this puzzle box is insane!

Special thanks to Chris Ramsay for sharing this with the world, Paul Brement of for designing and building it, and of course Riot for producing such a unique and memorable promotion.
