* Secret Rares are a specific type of rarity in the Yu-Gi-Oh! Trading Card Game. They are usually more powerful or unique cards, and are identified by a holographic background and a star on the bottom right corner of the card.
* Exodia the Forbidden One is a powerful monster card in Yu-Gi-Oh! It is comprised of five pieces: Exodia the Forbidden One, Left Leg, Right Leg, Left Arm, and Right Arm.
* While Exodia pieces can be found in Secret Rare versions, there is no specific set dedicated to them.
It's important to note that many custom cards and fan-made sets exist within the Yu-Gi-Oh! community. It's possible you've seen a fan-made set that includes Exodia pieces in a "secret rare" style.
