What Eeveeloution should I get?

[Blazeflyer]

Hello, everyone! I just beat Serra, which means I have 6 badges so for in the Reborn league. I just got the event Eeeve and I am having trouble deciding what I should I evolve him into. So, I would like to as for people's opinions after I give you all the Pokemon I rotate to better decide. Any help would be appreciated!

Sylveon is by far the best eevelution. You need a fairy type anyway, and Sylveon has a great niche with access to Misty Terrain, Wish, and tanking prowess

Strong Pokémon. Weak Pokémon. That is only the selfish perception of people. Truly skilled trainers should try to win with their favorites.

 

Sorry, I cannot get rid of this quote ;-)

As cool as Karen is, this is Reborn, and you'll never get that far with a Flareon or a Glaceon lol

[Raghav]

Sylveon with misty terrain or espeon with calm mind and psychic is pretty good and why your Arcanine doesn't know any physical fire type moves? I would say a good moveset for Arcanine would be flare blitz,heat wave,outrage/extreme speed,close combat

[SilverOwl271]

I’d also probably say Sylveon, especially since you don’t have a fairy type on your team yet. Really good special defense and a strong special attack make it pretty good. 
 

I like to try to give it at least protect, wish, moonblast, and a fourth move catering to fit/help your remaining team

Eventually you can get a ditto and breed so you will be able to get them all. Currently I agree with what other people are saying and to get a Sylveon. However I found that Leafeon has great synergy for later gyms so that would be a worthwhile investment, as would Espeon being the powerhouse it is.
