Steam Siege Card List & Price Guide (STS)
Every Steam Siege card with live raw and PSA 10 prices, updated hourly. Updated Nov 2, 2026.
Steam Siege arrived during the later XY period and centers on the clash of contrasting forces represented by Volcanion, Gardevoir and Steelix. Its defining gameplay feature is the return of Dual-Type Pokémon, supported by Pokémon-EX, Mega Evolution cards and seven BREAK cards. The leading chases are the secret rare Gardevoir-EX #116 and Volcanion-EX #115, followed by full-art versions of M Gardevoir-EX, M Steelix-EX and Gardevoir-EX. The varied rarity structure gives the checklist more depth than its reputation as a broadly available expansion suggests.

Adding up the lowest near mint Cardmarket price of every card gives about $396.69 for a raw set. Buying singles one by one usually costs more once shipping is added.
How many Steam Siege cards are worth more than $10?
9 of the 116 cards are currently worth $10 or more raw. Most of the rest are commons and uncommons that sell in bulk.
How do I find the card number on a Steam Siege card?
The number is printed in the bottom corner next to the set symbol and the set code STS. Match it to the list above, or scan the card with a phone app to read it for you.
What role do Dual-Type Pokémon play in Steam Siege?
Dual-Type cards carry two Pokémon types at once, allowing them to interact with effects and Weaknesses associated with either type. Steam Siege brought the concept back as a central visual and gameplay feature. Several prominent cards, including Volcanion-EX and shiny-themed Gardevoir cards, use the treatment.
Is Gardevoir-EX #116 the only secret rare in Steam Siege?
No. Steam Siege has two secret rares: Gardevoir-EX #116 and Volcanion-EX #115. Both use full-card artwork and sit beyond the regular numbered checklist. Gardevoir generally receives more attention, while Volcanion remains important to collectors completing the full secret rare pair.
Where do BREAK cards fit into a Steam Siege master set?
BREAK cards occupy their own rarity tier and feature a horizontal layout with gold-toned artwork. Steam Siege includes several, so they form a meaningful portion of a master set rather than a single novelty slot. Reverse holos, full arts and secret rares must also be tracked separately.
