Flint Lock

Flint Lock was introduced in the Tactical Evolution expansion set, released by Konami in the summer of 2007. As a common rarity effect monster, it was designed to support the niche Flint equipment archetype, allowing players to manipulate the placement of the Flint card to disrupt an opponent's field. The card reflects the mid-2000s era of Yu-Gi-Oh! where card designers frequently experimented with equipment-based synergies to add tactical layers to gameplay.

The card’s aesthetic and function were crafted to fit the mechanical theme of the Tactical Evolution set, which introduced Gemini monsters and expanded upon elemental synergies. While it did not achieve prominence in competitive play, it remains a recognized piece of the game's expansive history, valued primarily by collectors interested in the completion of early GX-era common sets.
