Ah, Flareon and Umbreon are good Eeveelutions; Flareon is a good Physical attacker, considering its Attack stat is high, and it can endure some Special Attacks with its high Special Defense. The design of Flareon is nice too, feminine if you ask me. Umbreon is a good Eeveelution if you're going to use a defensive team, since it has a good Defense and Special Defence, and it has a lot of HP. I personally like Jolteon, Umbreon (too), and Glaceon.
What do you think about Sylveon?
