Some chase cards are rare because of the card itself. Crystal Charizard is rare for two separate reasons stacked on top of each other.
The last set of its era
Skyridge arrived in 2003 as the final set of the e-Card series, released not long before Wizards of the Coast's license to produce the English-language Pokemon TCG came to an end. Collectors have long pointed to Skyridge's print run as reportedly much smaller than earlier sets, since the game was already transitioning to a new publisher.
A rarity tier of its own
Within Skyridge, a handful of Pokemon were given the "Crystal" treatment: a clear, prism-style holo pattern layered over the artwork, with each Crystal card numbered beyond the set's regular printed total, marking it as a bonus rather than a standard pull. Crystal Charizard sat at the top of that subset.
Two scarcities stacked together
A low pull rate for a Crystal card would be notable in any set. Stacked on top of Skyridge's own small overall print run, it made Crystal Charizard one of the hardest single cards to pull from any English-language Pokemon set of the era, and it's still discussed by long-time collectors as one of the toughest Charizard cards to track down in top condition.
