Daniel Madison's highly exclusive Hellions demonstrate a slightly different design than the Madison decks you know. The deck clearly has an evil character, which is reflected in different aspects. For instance, the front of the deck displays a devil's tail and text is printed in gothic style.
The backs are designed with high dedication to detail, which is typical for Daniel Madison. However, the fronts are different. They don't represent a repetitive pattern, but a hand-drawn, symmetrical appearance. Moreover, the decks is full of sinister surprises, which you'll discover, when getting hold of them yourself.
