Jokers from "The Great Creator" playing cards.
While doing my research for this deck, I stubbled upon this paragraph, which inspired me for design of Jokers.
"According to the creation story, An, the main God of the Ancient Sumerians saw that the labor on Earth was too great. The Son of An, Enki, proposed to create a species that would inhabit the planet and bear the labor and so the Gods created man. One of the Ancient Sumerian Gods was put to death and they mixed his blood with clay from Earth. Out of this material the first human was created in he likeness of the Gods."
