Lore

Why it matters

The Nidoking from the Aquapolis set is a notable example of the short-lived Crystal Type mechanic, which allowed the card to change its elemental weakness and resistance. Because the Aquapolis expansion was released toward the end of the e-Reader era, these holographic cards have become increasingly difficult to find in high-grade condition.
