This is the Oscura version for Omnia: The First series. The theme of the series is the concept of cyclicality, represented by a serpent eating its own tail. If you’re deeply intrigued by the idea behind this series, I urge you to explore the Kickstarter page (link provided at bottom).
This deck has an extra Queen of heart on gold back. Even though it’s supposed to be mirror image, take a closer look at the queen on the bottom. Spot the difference?
Let me include a youtube review done by Scrambled Decks. Although the zooming isn’t perfect for the entirety of the video, I like the details he explains. So much so that I subscribed to his channel. You should do so if you like such playing cards.
