Provenance

Where it came from

The Nidoking card from the XY—Steam Siege expansion was released in August 2016 as part of the Pokémon Trading Card Game. This set was designed to feature the dual-type mechanic, highlighting Pokémon that possessed two types simultaneously, which was a core theme of the competitive play environment at that time. The expansion drew its aesthetic inspiration from the Kalos region, incorporating mechanical and steampunk motifs into the card art to reflect the set's titular theme.

The artwork for this specific card was rendered by illustrator Kouki Saitou, who has been a prolific contributor to the franchise for many years. Saitou's design for this Nidoking leans into the creature's aggressive posture, emphasizing its role as a powerful, stage-two evolutionary form. Within the game, this card is a Psychic-type, a departure from the traditional Ground or Poison typing Nidoking usually holds, which underscores the unique mechanical focus of the Steam Siege collection.
