Unseen Forces is an expansion in the EX era of the English-language Pokémon TCG, with the set code UF. The release date was August 22, 2005, and the card list runs to 115 printed cards plus 2 secret cards, for 117 in all, with 143 printings catalogued once variants are counted. Its identity comes from the headline names: Lugia ex, the three star-marked Raikou, Suicune and Entei, and a run of ex cards led by Celebi ex and Umbreon ex. It leans on Psychic, Colorless, Grass and Water Pokémon.
The pull ladder in Unseen Forces is shallow in rarity labels, since most of the value sits in cards listed simply as Rare, with 26 Holo Rares beneath them, and the 2 secret cards numbered past the printed 115. Lugia ex is the most valuable card, followed by the star versions of Raikou, Suicune and Entei, all illustrated by Masakazu Fukuda, with Celebi ex next. Hikaru Koike drew the leading Lugia ex. Value is fairly concentrated: the top five cards hold 55 percent of the set's total card value, so a complete set is largely the price of those few cards.
As of October 2026, Unseen Forces holds the 3rd highest total card value of the 16 comparable EX sets, about 2.3 times the era median, and ranks 7th across the whole game's 130 comparable sets. Its most valuable card, Lugia ex, ranks 4th among the era's single top cards, while trading activity places the set 8th in the era. At 115 printed cards it sits about level with the era median of 107. It followed Emerald, which holds less total value, and came before Delta Species, which also holds less. Its cards first appeared in Japanese in Golden Sky, Silvery Ocean, released April 8, 2005, which shares 100 cards with it.

Finishing Unseen Forces means tracking down 143 catalogued printings, and all 143 are priced. Because the top five cards carry more than half the set's total card value, the cost of a complete set depends mostly on those headline cards, while the bulk of commons, uncommons and rares fill in around them. The sealed line includes 4 products: a booster box, a booster pack and two decks.
