A Deck created by ChatGPT using the prompt "Create a Legendary Fisherman Deck with a short description of the deck in Yu-Gi-Oh!"
Please bear in mind that as useful ChatGPT is it is by far not perfect. There will be inconsistencies and problems with deck building. Most of the time it will create a deck either under 40 cards or randomly have extra deck cards in the main deck. I've done some fine tuning whilst trying to not impact too much what ChatGPT has made.
A short description made by ChatGPT about how the deck functions.
The Legendary Fisherman archetype focuses on swarming the field with high ATK Fish-type monsters that can be difficult to get rid of, while also controlling the opponent's field with powerful trap cards. The deck's strategy revolves around using "A Legendary Ocean" to reduce the levels of all Fish-type monsters on the field by 1, allowing for easy access to the archetype's three main monsters: Legendary Fisherman, Legendary Fisherman II, and Legendary Fisherman III. Warrior of Atlantis is also a useful card to have in the deck, as it can search for "A Legendary Ocean" and "Salvage". Deep Sea Diva and Mermail Abysspike are included as additional ways to search for monsters, while Moulinglacia the Elemental Lord can disrupt the opponent's hand by discarding two cards.
The deck's trap lineup includes "Abyss-scale of Cetus" and "Abyss-scale of Mizuchi", which can protect the player's Fish-type monsters from being destroyed by battle or card effects, respectively. "Gozen Match" is a useful trap card that restricts the opponent to only controlling monsters of one attribute, which can be devastating against decks that rely on multiple attributes.
The extra deck is focused on providing additional options for the player, with cards like Bahamut Shark and Toadally Awesome allowing for easy access to powerful XYZ monsters. Mekk-Knight Crusadia Avramax and I:P Masquerena provide strong defensive options, while Union Carrier can equip an opponent's monster with "A Legendary Ocean" to disrupt their strategy. Crystron Halqifibrax and Apollousa, Bow of the Goddess offer additional ways to extend plays and protect the player's monsters, while Borrelsword Dragon and Borreload Dragon provide powerful offensive options. Black Luster Soldier - Soldier of Chaos and PSY-Framelord Omega offer additional ways to disrupt the opponent's strategy and protect the player's own cards.
