(Note: These are physical playing cards, and can be mixed and matched with cards from Series 1, Series 2, Series 3 and eventually Series 4, because they all have the same back image. :D)
(Note 2: Series 1 Double E is an ‘Enhanced Edition’ of Series 1, a complete redrawing of 52 original cards from the original set and two brand new ones!)
