Cover card

A cover card is a card shown in the background of a pack. It is usually the best card in the set, although there are exceptions. Some players believe that it is just a random card to give players a little show of the cards that can be found in the pack.

In Booster Packs and Structure Decks, the cover card is always an Ultra Rare card, except for a lapse in the TCG versions of the final four GX-era packs (Tactical Evolution to Light of Destruction) where the cover card is a Secret Rare as well as a Ghost Rare/Holographic Rare, in exception of "Yubel - The Ultimate Nightmare" (these alternate rarities follows in step with the OCG). It returns to original format matching with OCG starting with the first of the 5D's era packs (The Duelist Genesis) and has continued ever since.

Starting with OCG Series 4, the background color has followed an eight-color trend. The order in releases is green, yellow, red, orange, blue, purple, black and white. This phenomenon has come to be known as the "Booster Pack Rainbow" or simply "The Rainbow".
