Mythomagic

Mythomagic is a collectible card/figurine game played by Nico di Angelo. It involved trading cards and miniature figurines, and is focused on Greek mythology. The rules appeared to be very complicated, with similarity in rules to the rules of real-life card games like Yu-Gi-Oh and tabletop role-playing games like Dungeons & Dragons. When Nico met a mythological creature, he would often say something about their abilities within the game or whether or not he had that particular set. Nico's father, Hades is one of the strongest cards. In The Titan's Curse, Nico stopped Dionysus from attempting to kill Percy by speaking to Dionysus about his card and how it was considered the lamest god card by many other players, but he thought his powers were "totally sweet". In The Battle of the Labyrinth he is seen burning the mythomagic cards and calling it a childish game.



Hades Figurine
In Mythomagic, the Hades figurine was the only figurine that Nico didn't have. Bianca took one from The Junkyard of the Gods, causing Talos to awaken and costing Bianca di Angelo her life. Talos was a creation made by Hephaestus. Percy tried to convince Nico to take it by saying that it had 4000 attack power, but Nico corrected him by saying it had 5000, but only if the opponent attacks first.
