Deck was part of 2019 Mystery Deck sale from Seasons Playing Cards. This was a deck from the Uber-Rare tier. From forum on United Cardists, creator Alex Chin stated, Missing Island NPCCD Decks (Only 20 sets made). I was testing out making these as a puzzle where the missing clues were in the leftover pieces in your box the entire time! Twist! But in the end the puzzle never came through but still have these decks. Because they’re not diecut they’re actually more crisp than the actual full production deck.
