The movie was shot in 20 days, most of the fight scenes were done in less than 3 hours.

Although it's repeatedly stated that both Alpha and Omega each have 6 members, The Devil is supposed to be neutral, leaving the Omega team with only 5 members (even after the addition of The Fool).
Each team has 5 members: Alpha Team consists of Empress, Temperance, Hierophant, Magician, and Tower. The Omega Team consists of High Priestess, Chariot, Judgement, Emperor, and The Fool as the new hire. The Hermit acts as a wildcard with no specific affiliation. The Devil oversees operations and is also unaffiliated.
