Unseen Forces

The Unseen Forces Pokemon Card Set is a popular collection of collectible cards released in 2006. It consists of 102 cards, including 8 Secret Rare cards and 94 other cards divided into Rarity Levels. The Unseen Forces set is a Holofoil expansion featuring cards from the Delta Species series. It follows the same "evolution" style of the Delta Species series, which introduces Delta Species Pokemon as an evolutionary step from their existing counterparts. The set also includes a few cards from the e-Card expansion, such as the legendary Moltres and Zapdos.

The unique aspect of the Unseen Forces set is its rarity, as many of its cards can command high prices on the trading card market. The Secret Rare cards are especially valuable and include highly sought-after cards such as Blaziken ex and Charizard ex. There are also a number of rare Delta Species Pokemon which have become some of the most popular cards in the set. Many of these cards have been used in competitive tournaments, and they continue to be widely used by trainers.
