"Forbidden One", known as "Sealed One" (封ふう印いんされし, Fūinsareshi) in the Japanese version and also referred to as "Exodia" (エクゾディア, Ekuzodia), is an archetype of cards first released in Legend of Blue Eyes White Dragon and was the first group of cards to provide an automatic win. The main card, "Exodia the Forbidden One" (often referred to as "Exodia's head") is also one of the first five Effect Monsters ever to be released. The "Forbidden One" cards are some of the most iconic cards in the series, being well known for their Automatic Win effect and how, in the anime, Yugi was the first person to ever Summon "Exodia" (and in the first episode). While many people simply refer to these cards as "Exodia" cards, only the head of Exodia actually contains the name, while the other pieces are called "Forbidden One" in any card effect that refers to them; when used elsewhere on this page, "Exodia" refers only to the card "Exodia the Forbidden One" or the completed monster.
While the original "Forbidden One" set was extremely hard to obtain (all five pieces were Ultra Rare), they have since been reprinted in lesser rarities; a common practice is to print "Exodia" as an Ultra Rare and the limbs as Commons, making the set much easier to obtain. While the "Forbidden One" Deck was perhaps one of the first Deck types, it still remains a popular one, being supported through several new cards (specifically, new draw engines and draw loops).
