Question: What other game is comparable to Theatrix but uses playing cards as its randomiser?

Context paragraphs:
Karuta: Karuta (かるた , from Portuguese "carta" ["card"]) are Japanese playing cards. Playing cards were introduced to Japan by the Portuguese traders during the mid-16th century.  These early decks were used for trick-taking games. "Karuta" packs are divided into two groups, those that are descended from Portuguese cards and those from "e-awase".  "E-awase" originally derived from "kai-awase", which was played with shells but were converted to card format during the early 17th-century.  It is said that the earliest indigenous "karuta" was first invented in the town of Miike in Chikugo Province at around the end of the 16th century.  The Miike Karuta Memorial Hall located in Ōmuta, Fukuoka is the only municipal museum in Japan dedicated specifically to the history of "karuta".  Chinese playing cards of the money-suited and domino types existed in Japan from at least the late 18th century until the early 20th century.  Their games would influence those played with the "Hanafuda" pack.

Playing Cards Act: The Playing Cards Act is a law in Thailand that prohibits individuals from owning more than 120 playing cards that have not been registered by the Excise Department.  The current law was passed in 1943, superseding previous acts.  The Playing Cards Acts are part of Thailand's strict anti-gambling laws dating back to 1935.  To ensure legal possession of playing cards, under Section 12 of the law, a competent official has the power to enter anywhere between sunrise and sunset to conduct a search.

Theatrix (role-playing game): Theatrix is a role playing game produced by the defunct Backstage Press and no longer in print.  Primarily diceless, the game includes rules for using dice to resolve actions.  The game applies cinematic concepts to role-playing-- the players are "actors" and the GM is the "director."  The games attempts to frame adventures in the model of screenplays, which have a structured plot consisting of a number of agreed upon acts, scenes, and "pinch-points".  Players use plot points to guarantee success of an action or take minor control of the story.  This was a relatively new and controversial concept being championed by few in mainstream RPGs at the time of its release.  In addition to their numerically-rated attributes and skills, characters possess non-numerically-rated personality traits, and unrated 'descriptors'.  Descriptors can act as advantages, but in order to use them so, the player must spend plot points.  They can also act as disadvantages, and when they do so, the player gains plot points.  The game encourages collaborative roleplaying, using what it calls "Distributed Directing", whereby the players may introduce subplots though the GM remains responsible for directing the main plot.  Theatrix has many methods of resolving action and conflict without dice.  Most notabable is the use of extensive flow-charts, printed on card-stock.

German playing cards: German playing cards are a style of playing cards used in some parts of Central Europe.  Playing cards ("Spielkarten") entered German-speaking lands around the late 1370s.  After much experimentation, the cards settled into new suits of Acorns ("Eichel"), Leaves ("Grün" or "Blatt"), Hearts ("Herz") and Bells ("Schelle") around 1450.  Closely related Swiss playing cards are used in German-speaking Switzerland.  The French suit symbols were derived from the German ones around 1480.  German-suited cards spread throughout Central Europe into areas that were once under German or Austrian control (Hungary, Slovenia, Slovakia, Czech Republic, Croatia, Transylvania, Banat, Vojvodina, South Tyrol, Transcarpathia, and parts of Poland).  They were also produced and used as far east as Russia until the early 20th century.  German-suited decks are not well known all over these countries including parts of Germany itself as they have been undergoing strong competition from French playing cards since the late 17th-century.  Traditional card games in which the German suits are used include Skat, Schafkopf, Doppelkopf and Watten.

Kings (game): Kings (king's cup, donut, jug oval, of fire, or ring of fire) is a drinking game that uses playing cards.  The player must drink and dispense drinks based on cards drawn.  Each card has a rule that is predetermined before the game starts.  Many houses have their own variation of rules.

Standard 52-card deck: The deck of 52 French playing cards is the most common deck of playing cards used today.  It includes thirteen ranks of each of the four French suits: clubs (♣ ), diamonds (), hearts (♥ ) and spades (♠ ), with reversible "court" or face cards.  Some modern designs, however, have done away with reversible face cards.  Each suit includes an ace, depicting a single symbol of its suit; a king, queen and jack, each depicted with a symbol of its suit; and ranks two through ten, with each card depicting that many symbols ("pips") of its suit.  Anywhere from one to six (most often two or three since the mid-20th century) jokers, often distinguishable with one being more colorful than the other, are added to commercial decks, as some card games require these extra cards.  Modern playing cards carry index labels on opposite corners or in all four corners to facilitate identifying the cards when they overlap and so that they appear identical for players on opposite sides.  The most popular stylistic pattern of the French deck is sometimes referred to as "English" or "Anglo-American" pattern.

King (playing card): The king is a playing card with a picture of a king on it.  The king is usually the highest-ranking face card.  In French playing cards and tarot decks, the king immediately outranks the queen.  In Italian and Spanish playing cards, the king immediately outranks the knight.  In German and Swiss playing cards, the king immediately outranks the Ober.  In some games, the king is the highest-ranked card; in others, the ace is higher.  Aces began outranking kings around 1500 with Trappola being the earliest known game in which the aces were highest in all four suits.  In the Ace-Ten family of games such as pinochle and schnapsen, both the ace and the 10 rank higher than the king.

Diceless role-playing game: A diceless role-playing game is a role-playing game which is not based on chance: it does not use randomisers to determine the outcome of events in its role-playing game system.  The style of game is known as "diceless" because most games use dice as their randomiser; some games such as "Castle Falkenstein" use other randomisers such as playing cards as substitutes for dice, and are not considered "diceless".

Jerry's Nugget playing cards: Jerry's Nugget playing cards were supposedly printed in the 1970s for the gaming tables, but never saw any action at the gambling table.  They were immediately sold in the gift store thereafter.  The classic Jerry's Nugget playing cards were made from top of the line United States Playing Card Company card stock, that is not available today, which makes the cards much thinner than today's playing cards.  The Playing Card Company also used a chemical finish then, which is also not available today due to environmental reasons.

Archaeology awareness playing cards: The archaeology awareness playing cards are a set of playing cards developed by the United States Department of Defense designed to educate members of the United States military serving in Iraq and Afghanistan about the importance of respecting ancient monuments, to try to preserve the Iraqi and Afghan national cultural heritage.  The goal of the publication of the cards was two-fold according to Fort Drum archaeologist Laurie Rush - to prevent unnecessary damage to ancient sites and to stem the illegal trade of artifacts in Iraq.  The military has long recognized that educational playing cards are a good way to capitalize on the time soldiers spend waiting for orders.
