Picture a corridor that rewrites itself every time you walk—doors that open to a room you’ve never imagined yet always echo the same haunting melody. The twist? Each step is a card; you draw it and the floor morphs into a trap, a puzzle, or a portal to another time. One card could trigger a sudden illusion of endless stairs, another a sudden shift into an inverted world where gravity is a suggestion, and a third could lock the door behind you while the walls bleed ink. Keep the cards hidden in the floor tiles, but make them look like ordinary cobblestones so the adventurers think they’re just following a path. Every choice becomes a gamble; the dungeon itself is a living deck that loves to keep you guessing.
