Question: yugioh what are structure decks?
Answer: A Structure Deck (Japanese: ストラクチャーデッキ Sutorakuchā Dekki) is a retailed pre-made Deck designed to be playable straight from the box without any modification needed. It is similar to a Starter Deck, but is focused on a certain Type, Attribute, Archetype, strategy, or Yu-Gi-Oh! character.
