There are two black jacks in each deck of cards. There is a jack of spades and a jack of clubs. Each deck of cards has two suits that are black, spades and clubs. Each deck also has three face cards (cards that depict a person), jack, queen and king, for each suit. Therefore, there are two black jacks (jack of a black suit) in each deck of 52 cards.
