Enhancement Packs are Booster Packs of typically predetermined cards used to randomize their rarities: the packs have been included in most OCG Starter Decks and Structure Decks since Starter Deck 2013 (barring Structure Deck Rs until Structure Deck R: Dragunity Drive), but they are not sold separately. The TCG counterpart is the Power-Up Pack, but these have been generally discontinued: instead, pack contents are included directly in the corresponding sealed product, at a non-variable rarity.
