Many collectors love these decks, and I count myself among them they are easily among my favourites, due to the incredible creativity and ingenuity that is required to make them. Pictured below is an example featuring the Seven of Diamonds, where the diamond pips have been incorporated into the artwork as the lids and sides of different boxes and into a swing.
To illustrate: the pips on a Five of Hearts might have facial features added to them, and so be transformed into human faces that are part of a larger image picturing five people. Decks where the pips aren't in the expected position/colours are sometimes referred to as semi-transformation decks. Typically these pips use their traditional location on the card and their traditional red/black colours. You don't know what a transformation deck is? It is a unique deck of playing cards where the pips have been incorporated into a larger artistic image. Transformation decks have been a popular novelty for almost as long as playing cards have existed. Special Content by BoardGameGeek reviewer EndersGame Concept
