Crystal Guardians cards originate from the EX Crystal Guardians Pokémon TCG set, launched in August 2006 as part of the EX Series, which notably introduced the powerful -ex cards and Delta Species mechanic. This unique set focused on the secret city of Holon, presenting Delta Species which allowed for type variations on familiar creatures, significantly enhancing strategic gameplay. Beyond powerful -ex cards, the set also incorporated distinctive Trainer cards.
Today, the set holds significant value due to its age and limited availability, making many of its cards highly desirable. Its collectibility is further boosted by the presence of highly sought-after “Star” cards, which are exceptionally rare and iconic. The innovative concept of Delta Species also contributes to its appeal among collectors.
