Assumption is a fictional variation of
Poker created and featured in the novel
Last Call by
Tim Powers.The simplest explanation of the game is that it is playing Poker with a
Tarot deck instead of a standard playing deck, using the four tarot suits (Cups, Wands, Swords, and Pentacles) instead of the standard suits (Diamonds, Spades, Hearts, and Clubs), and discarding the Major Arcana Cards. This increases the deck size to 56 cards instead of the standard 52 due to the addition of Knight Cards not present in a standard playing card deck. Betting and dealing are described as much the same as a regular round of poker amongst a dealer and players.
