Mollymauk Tealeaf's tarot deck

Mollymauk Tealeaf's tarot deck is a set of Moonweaver cards, a specific tradition of tarot or oracle card deck. Like all Moonweaver cards, the cards are created personally by the owner, and each deck is thus unique. After Molly's death, his deck passed into the ownership of Beauregard Lionett. She kept it for a while before giving it to Jester Lavorre, who began to illustrate new cards and use it to read fortunes.

Description
Molly's tarot deck is a Moonweaver deck, a tradition that differs from other tarot or oracle card deck systems in Exandria. As the Moonweaver fosters creativity and deceit in their followers, Moonweaver decks tend to be wildly varied. These decks do always include a Moon card, and each card is designed so that there is a word at the top and bottom of each face, so that the card is different when reversed; the name of the card is the word at the bottom. Each card is also numbered.

Molly's deck included cards that are damaged and difficult to read due to age, with unfinished or abruptly stopped sketches, and have blank faces in anticipation of new additions. The deck was described as "an ongoing art project" that evoked a distinct sense that it was created, not purchased.

The following are cards as depicted in Critical Role, many of which do not have confirmed reversed sides within the game. For the cards as they appear in the real-life deck, see "Oracle of the Moon deck".

Mechanics of use
Fortunes were typically told using a three card spread: the first to represent the past of the querent (the one whose fortune is being read), the second to represent the present, and the third to represent the future.

When Molly "read" fortunes, he did so through an Insight check to cold read the subject and a Sleight of Hand check to force an appropriate card. Molly would also stack the deck beforehand to facilitate this.

When Jester read fortunes, Laura and Taliesin developed a system where the querent rolled a d20 to select a card, then a d6 to determine which side was upright; though this was the intended process, the d6 roll was often forgotten. When used in this manner, the following rolls produced these cards:
 * 1: The Tyrant
 * 8: The Eye and the Hand, a 2 on the d6 places the Eye upright
 * 9: History and the Dream
 * 11: Home and Traveler
 * 18, then 1: Death

The deck was also sometimes used to play games. One such game, which Molly and Beau played, involved each participant drawing a card and whoever drew the higher or lower card, as decided before the draw, must answer a question. Drawing a card was simulated by rolling a d20.

Molly's ownership
Molly enticed Jester into paying two copper pieces to have her fortune "read". For her reading, Molly drew the Judge, the Anvil, and the Serpent and informed her that she already found that which she sought. He later entertained a crowd outside the tent of the Fletching and Moondrop Traveling Carnival of Curiosities with fortune reading. Seeing Jester entering the tent, he pulled the Shadow and the Moon from a stacked deck and asked her if they meant anything to her. She said yes, and he instructed her to think about it.

As part of casting Vicious Mockery, Molly drew and presented the unidentified card drawn from the bottom of the deck, warning in Infernal: "There is only death here." The deck made later appearances: a failed attempt to entice children to encourage their parents to stop for a reading, a fortune claiming Jester came from a "primordial chaos magic" and was heading down a new path toward an unexpected destiny, and deflecting suspicion by offering fortunes to passing Crownsguard during an infiltration of the Sutan residence.

Caleb asked Molly if his cards were "bullshit", to which Beau agreed and Jester protested. Molly responded that they were not but smiled smugly at Caleb behind Jester's back, suggesting Caleb's suspicion correct. In his final days, Molly unsuccessfully attempted to perform a new sleight of hand trick to exchange the Moon in his hand with a moon-themed trinket to amuse Ombo, saying that it was a trick he was working on, and enticed Beau into playing a game: whichever of them drew a lower numbered card must answer the question "what's the best lie you've ever told?"

Beau's and Jester's ownerships
After Molly's death, Beau took the deck from his jacket before she, Caleb, and Veth bury him. She later offered Jester Molly's deck to draw from while the group visited his grave. Jester drew the Moon and, feeling that it is Molly's card, left it there. Months later, Beau searched the deck for the card illustrated with the All-Seeing Eye to provide Orly Skiffback a reference for her gemstone tattoo. The tattoo incorporated both the eye and a filigree design from the cards.

Shortly after, Beau and Jester had a dispute over the authenticity of Molly's tarot card readings: Beau pointed out that Molly was aiming a vague wide spread to seem correct while Jester believed that his readings were genuine. Beau gave Jester the deck, and Jester spent the rest of the day attempting to learn to read fortunes. She attempted this by looking at the cards to discern their meaning intuitively by looking at them. Jester researched tarot decks at the Cobalt Soul Library in Rexxentrum. She learned that Molly's deck is a Moonweaver deck and the traditions surrounding this specific type of deck. However, she learned little in the way of using the deck to read fortunes. Veth later purchased card stock for to use Jester to add to the deck. Jester created the Hag and the Maiden as well as the Jewel and the Thief, the Spark and Blaze, and Death and Dawn. She read Fjord's fortune, drawing the Eye for his present and Home and Traveler for his future. Though Jester and Nott were enthusiastic about the fortune, Fjord was unconvinced and bewildered.

As the Nein debated how to proceed through Eiselcross, Jester drew a card from the deck for a sign. She drew the Magician, and she told the group that, before he died, Molly created cards depicting each of the Nein at the time. She later created Growth and Rot while keeping watch after exploring some ruins of Aeor. After the Nein were forced to travel with the Tombtakers, Jester offered to read Lucien's fortune. Though he initially agreed in good humor, the reading unsettled him. She drew the History for his past, the Tyrant for his present, and Death for his future. When he reacted to Death, she attempted to offer a reading that Death refers to a transformation of the self and a rebirth rather than a literal death.

In the later battle with Lucien, she called out to Molly and referenced this fortune, particularly the connotation of Death meaning to be reborn. Lucien scoffed, saying that the deck was always stacked and the fortunes were only storytelling to say what one wanted to hear. Using her connection with Cognouza, Veth apparated a spread of three cards from Molly's deck before Lucien, showing him the Judge and attempting to remind him that he was "a good person".

After Lucien's death, Jester used the deck to make an offering during a Raise Dead resurrection ritual for Molly. She informed him that she added new cards, believing that he will be impressed with her work, and asked him to come back so that she could learn how to read fortunes, adding furtively that she was making it all up. The soul returned to the body identified the Nein by the names of the cards depicting them: Love, Magician, Tinkerer, Joy, Sea, and Rumor. Jester attempted to communicate to the newly raised soul using the cards depicting Molly and the other members of the Nein. Later, when the soul, identifying now as Kingsley Tealeaf, did not recognize the Nein, Jester showed him these cards again. Kingsley did not recognize the cards.

In October 2022, the Critical Role Productions began selling an oracle deck based on Molly and Jester's deck. It has the following cards, most of which are as described in Critical Role (see "Description" above):
 * The Anvil and the Sword
 * The Eye and the Hand
 * Moon and Mirror
 * Tavern and Lust, by Molly, depicting the Gentleman
 * Dream and History
 * Sacrifice and Hunger, by Molly, depicting a skeleton (Sacrifice) running a pole through the throat of a wolf (Hunger)
 * Growth and Rot
 * Bond and Betrayer, by Molly
 * Home and Traveler
 * The Judge and the Tyrant
 * The Fool and the Soldier, by Molly, depicting himself
 * Joy and Chaos
 * Love and Temple
 * The Sky and the Sea
 * The Book and the Rumor
 * Tinker and Magician
 * Spark and Blaze
 * Jewel and Thief
 * Death and Dawn

Trivia

 * The name of the card depicting Molly is never given. Following the pattern that each of the Nein were called by the names of the cards depicting them in, Molly possibly depicted himself on a card named Empty, in reference to his origins.
 * Four of the cards share names with real-world Major Arcana cards: the Moon, the Chariot, the Magician, and Death.
 * Jester drew the Chariot from Molly's deck because Taliesin held out a physical tarot deck as a prop at the table for Laura to do so. The deck Taliesin used, with intricately detailed blue-and-white card backs and the Chariot depicting a figure dressed in red and brown over a blue triangle, appears to be the Aquarian Tarot by David Palladini.
 * Though Jester illustrated a Death card very different from that of the real-world Death, the connotation she explained to Lucien matches the connotation of the real-world Death: it heralds transformation of the self and a rebirth, of something ending to make way for something new.
