Cloudian - Poison Cloud

Cloudian - Poison Cloud was released in the 2007 booster set Gladiator's Assault as part of the Cloudian archetype. Designed by Konami for the Yu-Gi-Oh! Trading Card Game, this set introduced the Water-attribute Cloudian monsters, which were themed around mystical, weather-based creatures that utilized 'A-Counters' to maintain their presence on the field. The design reflects the series' expansion into specialized counter-based mechanics intended to reward players for maintaining a stable board state.

The card was illustrated with a distinct aesthetic characteristic of the mid-2000s era of the game, featuring a stylized, ethereal cloud creature designed to embody the defensive nature of the archetype. While common in rarity, the card was widely distributed to provide players with a reliable, albeit situational, monster that could facilitate the Cloudian strategy of stalling and attrition. It remains a representative example of the tactical variety introduced during the GX-era expansions.
