Duel Decks are a series of pre-constructed decks for the trading card game Magic: The Gathering. Each set typically features two themed decks that are designed for direct play against each other, making them ideal for new players and casual games. These decks often highlight specific mechanics, characters, or storylines from the Magic: The Gathering universe. Released periodically, Duel Decks provide an accessible way for players to experience the game without needing to build their own decks from scratch.
