The Mega Dream EX complete set featuring iconic cards like Mega Gengar EX and Mega Charizard X EX encapsulates a pivotal era in the Pokémon trading card franchise, which saw significant popularity spikes during the late 2010s.

Collectors value this set not only for its powerful gameplay potential but also for its nostalgic appeal from the Pokémon anime series that debuted in the mid-1990s.

Although in used condition with minor scratches and signs of wear, these cards maintain strong demand due to their limited print runs and the esteemed reputation of the Japanese production quality, which often outperforms international prints.

As such, the current bid of ¥14,000 reflects the competitive market for these collectibles among dedicated enthusiasts in Japan.
