Berner's Major Arcana deck, a suit of 22 cards, was commissioned by the Swedish company Leonleija Design. The deck retains the traditional cards used in fortune telling - Judgement, The Hanged Man, The Devil - but replaces the expected imagery of cadavers and demons with illustrations of teapots, courting monkeys and conical flasks.
"I wanted fresh designs that would speak to people who are not into that magical world of tarot," Berner says. "If you don't see yourself as someone who goes to tarot readings, then the aesthetic is really important. You might take this new set out if your friends came over, but older, more sinister decks maybe you wouldn't."
As well as redesigning the aesthetics of the deck, Berner and Leonleija also altered the basic form of the cards. Whereas traditional tarot cards require someone familiar with the pack to "read" each selection, Berner's deck includes brief printed descriptions of each card, allowing non-experts to understand their significance.
"It's really strange that the interpretation should always be in the hands of the owner of the card deck," says Berner. "So we put text on the cards so anyone can use it and you have an interpretation there for you. It's really easy. You can use it when you have friends over as a game. You don't have to take it too seriously.
"It's a bit of fun, although people always still seem to get a bit serious after a while. Maybe that's good. Tarot is about progressing in some way in your life. So while I don't think you should take it too seriously, if it helps you to see things more clearly in your life then maybe that's good."
The strength of Tarot lies in Berner's adaptation of a minority pastime into an accessible social activity. The only trace of tarot's familiar macabre side in Berner's deck is The Death card: a skull with clover blooming from its eyes.
"It's actually a really positive card," says Berner. "It's a good one to get. It's just about leaving something behind and entering something new. It's a fresh start."
