| Structure Deck
|Japanese (base text)||
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. It is designed to be playable straight from the box - no other cards are necessary in order to use the deck.
The older Decks always 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).
As opposed to Starter Decks (with the exception of Duelist Toolbox, V for Victory, Space-Time Showdown, and Yuya), Structure Decks may include multiple copies of the same card. This is because Structure Decks are designed with a focused strategy in mind, unlike Starter Decks, which are made to learn how to play. The mat included also features the cover monster in the background somewhat blocking the visibility of the card zones.
After a Structure Deck is released, the Booster Packs that follow it typically include cards that support the Structure Deck's themes. Another popular way to power up a structure deck is to buy multiple copies of a single Structure Deck and combine the Deck's best cards into one.
