The Steelix Constructed Standard Deck (Japanese: 構築スタンダードデッキ ハガネール鋼Pre-built Standard Deck Haganeil Metal) is a Japanese-exclusive Standard Deck that complements the Reviving Legends expansion of the Pokémon Trading Card Game.
Information
The Standard Deck contains several cards that could not be found in the main expansion. When released in English, all Pokémon featured in the deck were included in the Undaunted expansion with the exception of Onix and Steelix, which were released in the earlier Unleashed expansion. These cards and the deck in general inspired the basis for the Unleashed expansion's accompanying Steel Sentineltheme deck.
