Trump card: A trump card or trump is a playing card elevated beyond its normal rank.

Trump (card games): A trump is a playing card which is elevated above its usual rank in trick-taking games. Typically, an entire suit is nominated as a "trump suit"; these cards then outrank all cards of plain (non-trump) suits.  In other contexts, the term trump card can refer to any sort of action, authority, or policy which automatically prevails over all others.

Fame and Fortune (TV series): Fame & Fortune is a game show broadcast on RTÉ One on Saturday nights between 1996 and 2006.  Presented by Marty Whelan (who signed off every show with the catchphrase: "How do you play?  You buy a ticket.") , the show aired during the summer months of June, July, and August as a seasonal replacement for "Winning Streak".  It was preceded by "Millionaire", also hosted by Whelan, and succeeded by "The Trump Card" in 2007, hosted by Laura Woods.  "Fame & Fortune" had its production costs funded by RTÉ and its prize money funded by Ireland's National Lottery.  Entry to the show was based on National Lottery scratchcards, and contestants could win cash, cars, holidays, and other prizes.  "Fame & Fortune" had its final season in the summer of 2006.  Its 2007 replacement, "The Trump Card", was itself replaced a year later by "The Big Money Game".

The Trump Card (book): The Trump Card: Playing to Win in Work and Life is a 2009 book by Ivanka Trump.

Ivanka Trump: Ivanka Trump ( born Ivana Marie Trump; October 30, 1981) is an American television personality, fashion designer, author and businesswoman who is an advisor to the President of the United States, Donald Trump.  She is the daughter of the president and his first wife, former model Ivana Trump.

Ruff (cards): In trick-taking games, to ruff means to play a trump card to a trick (other than when trumps were led).  According to the rules of most games, a player must have no cards left in the suit led in order to ruff.  Since the other players are constrained to follow suit if they can, even a low trump can win a trick.  In some games, like Pinochle and Preferans, the player who cannot follow suit is required to ruff.  In others, like Bridge and Whist, he may instead discard (play any card in any other suit).  Normally, ruffing will win a trick.  But it is also possible that a subsequent player will overruff (play a higher trump).  This is not always a bad thing—see uppercut below.

Uppercut (bridge): In contract bridge, an uppercut is a defensive play that involves one of the defenders ruffing high in the knowledge that an overruff by the declarer will result in the promotion of a trump card in his/her partner's hand into a winner.  Thus, the technique presents a type of trump promotion.

The Sun (Tarot card): The Sun (XIX) is a trump card in the tarot deck.  Tarot trumps are often called Major Arcana by tarot card readers.

Joker (playing card): The Joker is a playing card found in most modern card decks, as an addition to the standard four suits (clubs, diamonds, hearts and spades).  The Joker originated in the United States during the civil war and was created as a trump card for the game of Euchre.  It has since been adopted into many other card games where it may function as a wild card.  The card is unique in that it lacks an industry-wide standard appearance.
