In the Yu-Gi-Oh universe, a "Special Edition" is a product that offers a few booster packs for the trading card game. Along with the booster packs, these Special Editions also contain some exclusive cards.
Through the Cybernetic Horizon Special Edition, you'll receive 3 booster packs. This item was released in September 2018. The cards in this pack are related to the Cybernetic Horizon pack. Even the variant cards are from the Cybernetic Horizon game addition.
While only 2 cards have been chosen from this game addition, only 1 of them is available in any Special Edition product.
This is not all, for 2 cards from, at the time, upcoming boosters were also chosen as previews to be released through this Special Edition. However, players would still only find 1 card out of the 2 in the box.
