In 2015, KaBOOM! published a six-issue mini-series titled Adventure Time with Fionna and Cake: Card Wars .
: Originally released as single-issue comics, it has since been collected into trade paperbacks.
Before diving into the Fionna and Cake iteration, we must remember the origin. Card Wars is a highly complex, collectible card game (a parody of games like Magic: The Gathering or Yu-Gi-Oh! ) played throughout the original Adventure Time . The flagship episode, "Card Wars" (Season 4, Episode 14), saw Jake ruthlessly defeat Finn using an overpowered "Fluffy Pig" strategy, leading to one of their most memorable sibling rivalries.
