I have all the eevee evolutions and I'd say umbreon buts that's my opinion and its the hardest to evolve. Glaceon pretty good though if you teach it blizzard , ice beam , aurora beam and hyper beam buts that's just my opinion
hope I helped!
Its evolve to Vaporeon from eevee
Evolve it from eevee
an eevee
Eevee will not evolve because there has not been a new Pokemon invented in which eevee can evolve into.
it can evolve eevee into a flareon.
you can evolve pikachu into Raichu and Eevee into Jolteon
Eevee
eevee
eevee,
Ive hear my friends say that in Pokemon yellow you can evolve eevee in a espeon with a moon stone
Max out Eevee's happiness during the day. ~KKMG1
You use a water stone on your Eevee.
