Which Eevelution is best for my party?
I have Gabite, Kirlia, Luxio, Monferno and Eevee.
The Bibarel I plan to get rid of soon.
I was thinking of evolving it to a Vaporeon. What do you guys think? Do you think there is a better option? Where can I find a water stone or trade my blue shard?
Well, you already have Fire, Psychic, and Electric covered. So that limits your options a bit. The only good ones out of the remaining ones are Vaporeon and Umbreon. Both are useful, but Vaporeon is better.
Yeah, originally I thought about getting an Umbreon but then along the way I caught a Ralts, which I am now debating whether I should evolve it to Gallade or Gardevoir. The choice would be easy if Platinum had Fairy typing available.
So, where can I find a water stone? At what level should I evolve my Eevee into a Vaporeon?
>not having a party made up exclusively of pokemons from that generation
I like Umbreon best, but Vaporeon would probably be good for your team too if it's your favorite.
If you prefer Umbreon, then get Umbreon. You're playing against the CPU here. You can handle not having a water type. I've been just fine with way worse teams, including single-type.
