Black Power expresses a range of political goals, from defense against racial oppression, to the establishment of social institutions and a self-sufficient economy. The earliest known usage of the term is found in a 1954 book by Richard Wright entitled Black Power.
In the poker game of Texas Hold'Em only one deck of cards (52 cards) is used for the entire game. Same goes for other variants such as Omaha, Stud, Draw poker etc.
In a standard deck used for bridge, poker and other games, there are 52 cards (4 suits, 13 cards per suit). There are also two jokers, because some card games use one or two jokers in the game. So sometimes you could say there are 54 cards in the deck, even though most card games don't use the jokers.
