The deck started with a full 22 cards.
Felix Fortunefan pulled the first card, and just so happened to draw the Moon card. His wish was to become a great mage, like those in the Hydra Collective. 21 cards remained.
He encountered Calliope after the Battle of the Bards in 1113 GE. He offered Calliope to draw from the Deck of Many Things. Calliope pulled Idiot, dropping his Intelligence to 6. He then pulled the Fool card, garnering no effect. Forced to draw again, he drew Talons. All of his magic items, including the Staff of Peaks and Valleys ("Shovel"), disintegrated. Swansong simply vanished, severing his attunement and suspending their bonding. Calliope, needing a win, drew a 4th time, and got Gem. A cauldron filled with 50 gemstones worth 1,000 gold each landed on his head (Session 063). 17 cards remained.
