Released in 2010 as part of the HS—Undaunted expansion, the Pokémon Gloom card (number 27) holds a specific place in the trading card game's history. This Stage 1 Grass-type Pokémon evolves from Oddish and is featured here with the distinctive Reverse Holo treatment, which adds a shimmering foil effect to the card's background without altering the central illustration. Designed by Mitsuhiro Arita, the card retains the classic layout typical of the HeartGold & SoulSilver era, emphasizing the Pokémon's stats and abilities clearly against the textured backdrop. Gloom serves as a versatile option in the TCG due to its unique ability, Miracle Powder. This attack allows players to flip a coin; if successful, the player can choose one Special Condition to affect the defending Pokémon. This mechanic makes the card a strategic choice for decks looking to disrupt opponent strategies rather than relying solely on damage output. With 80 HP and a retreat cost of only one energy, Gloom offers surprising durability and mobility on the battlefield, allowing players to switch it out easily when the situation demands. Gloom appears as card number 27 in this set, marked as an Uncommon rarity. The Reverse Holo variant is particularly sought after by enthusiasts who appreciate the contrast between the matte card surface and the glittering foil pattern. Completing a full set of Undaunted Reverse Holos requires tracking down this card among the diverse roster of Pokémon included in the expansion. The product represents a tangible piece of the franchise's card game evolution, appealing to both nostalgic fans and new players exploring the TCG's rich lore and mechanics.

Flip a coin. If heads, choose 1 Special Condition. The Defending Pokémon is now affected by that Special Condition.
What appears to be drool is actually sweet honey. It is very sticky and clings stubbornly if touched.
