How rare is sylveon?

Sylveon, a Fairy-type Pokémon introduced in Generation VI, is relatively rare in the Pokémon games compared to more common species. Its rarity can vary depending on the game; for instance, in Pokémon GO, Sylveon must be evolved from Eevee with a specific set of conditions. In main series games, Eevee can be found in various locations, but obtaining Sylveon specifically requires leveling up Eevee with high friendship. Overall, while not the rarest Pokémon, Sylveon can be less frequently encountered than many others.
