Laval Miller

Laval Miller was released as part of the Hidden Arsenal 5: Steelswarm Invasion booster set, which hit North American markets in 2012. This set was designed to introduce various Duel Terminal archetypes to the Western TCG audience, specifically focusing on the Laval monsters, which are centered around graveyard manipulation and fire-attribute synergy. The cards in these sets were imported from Japan's OCG and were notable for their distinct card frame styling and foil treatments, which differed from the main-series booster sets of the time.

The card features an illustration consistent with the thematic aesthetic of the Laval tribe, characterized by mechanical, molten-core designs that emphasize the faction's volcanic origins. Like many cards in the Hidden Arsenal series, Laval Miller serves as a utility monster intended to support deck thinning and graveyard setup. While it did not become a dominant competitive staple upon its release, the card is recognized by collectors as a foundational piece of the Laval archetype, representative of the era's focus on complex graveyard-dependent engines.
