Kecleon

Kecleon is a Normal-type Pokémon card from the 2009 Rising Rivals expansion, featuring the color-changing chameleon Pokémon that has moderate recognition among fans but isn't considered a flagship character. As a common card from a 15-year-old set, it typically sees minimal collector interest outside of set completionists. Recent pricing has experienced dramatic volatility with a 129% spike over 30 days, representing a significant departure from typical market patterns for cards of this rarity and character popularity.
