Lugia

Lugia is a legendary Psychic/Flying type that's been a mainstay of the TCG since the Gold/Silver era. As one of the original box-art legendaries, it carries serious cultural weight in the hobby—players and collectors remember opening boosters hoping for this card. Its dual typing and mythical ocean guardian aesthetic have kept it relevant across multiple generations of print runs. Lugia cards span the entire TCG timeline, meaning supply varies wildly depending on the set and era. Earlier printings command attention from vintage hunters, while recent versions tend to be accessible. The species shows up regularly enough that demand has to compete with availability, but the legendary status keeps it from ever being completely forgettable in a collection.
