The 59th Card Wars Doubles Classic is a tournament that Jake and his daughter, Charlie, participated in. The annual event was first seen in the episode "Daddy-Daughter Card Wars," during its 59th run. The tournament's spectators are mostly Turtle People, with the Turtle Announcer providing commentary for the matches. The tournament goes by a point system, so one could draw a game with one team still being able to advance.
The tourney takes place at an abandoned oil rig, and everyone's boats are docked around it during the tournament.

The only battle seen during the first round is between Team Dignified, who is Jake and Charlie, and Reggie and Pete the Punk. The match begins with Jake flooping his Haybarn and sending his Hayman to attack. This move is countered by Bean Ball bomba, destroying his Haybarn, weakening his Hayman. Charlie ends the round by Infinite Hay Maker.
Jake and "Charlie" play the semi-finals, with an unknown interval between the previous rounds. Due to Mr. International giving Jake a close game, Jake decides to force a draw, much to everyone else's disapproval. It is referred to as a "garbage win" from Turtle Announcer.
The Final for the 59th Card Wars Doubles Classic is played by Team Dignified against the reigning champions, Grand Prix and Moniker DeLuise. During an intense match, Grand Prix and Moniker come out victorious. Jake shows maturity shaking the victor's hand calling it a good game.
- Despite being a tournament that matches together two teams at a time, there are only seven teams seen.
