A Structure Deck (Japanese: ストラクチャーデッキ Sutorakuchā Dekki) is a retailed, pre-made Deck. It is similar to a Starter Deck, but is based on a certain Type, Attribute, strategy, or Yu-Gi-Oh! character. Each Deck is designed to be playable straight from the box. The older Decks included at least one single new card, printed as an Ultra Rare; after the Curse of Darkness Structure Deck, they always introduce 5 new cards, 1 or 2 of them being Ultra Rare, 2 of them Super Rares, and the remaining 2 as Commons (usually Spells or Traps).
