Mystery is a community event with a series of unique interactions and puzzles. It was first initiated in the Forged in the Barrens expansion.

To access a Mystery, the player needs to play a game in Practice mode, preferably Normal difficulty, then play a certain number of collectible cards in a certain order. At the end of their turn, the player will then get a ??? card with a ? bubble art, which transfers the player to a puzzle when played. During a puzzle, all normal gameplay rules are not applied and replaced with the puzzles' rules. Almost all cards in each puzzle are ??? with ??? text, which requires the player, or a group of players to figure out the functionality of the cards and solve the puzzle together.

Completing a puzzle will give a point progress towards the ??? achievement in Gameplay section. Completing all of the puzzles of an expansion will reward the player a unique card back.
