Description from the website: This delightfully wicked playing card deck presents devilish boys and ghouls and all manners of ghastly creatures. Inspired by vintage transformational decks, Royal Mischief’s suit marks are mischievously hidden in the aberrant artwork by infamous tarot artist Patrick Valenza. The sepia-toned poker deck features graphite gilded edges to complement the hand-drawn pencil artwork. 54-card deck includes two naughty Jokers and comes in a substantial two-piece box, perfect for giving as a gift to frenemies. Warning: Not for sensitive souls and delicate dispositions—this little deck bites! Published by US Games Systems. Full Deck Scan: https://cardscans.piwigo.com/index?/category/349-royal_mischief

This self-published medieval styled deck consists of 54 cards including two naughty Jokers, from Patrick Velenza (Deviant Moon) in a style similar to his well received 2008 tarot deck Deviant Moon.  Per direct update from the artist, just 500 were printed (original plan as mentioned via twitter of 777 was reduced in actual printing).  Patrick was also known to include 2 randomly selected transformation cards (out of a confirmed 28 available) which he created that have the same back as the deck with each order.  The deck came shrinkwrapped with the seal on the shrinkwrap with any bonus transformation cards added outside of the tuck in the shipment packaging.
