I say they're the same because umbreon can beat espion and espion can learn psychic and it's very powerful but can't hurt dark types.
first go to your house and check if it is pm. if it is then train it and it will evolve into an umbreon but if it say am it will be a espion
to get an espion you have to give your eevee alot of love and care. The man dr footstep will tell you how much you Pokemon likes you. when it likes you ALOT go and level up your eevee. To get sn espion you must lv up in day and to get umbreon you must lv up at night
you have to level it up in the day until it loves you. for umbreon you have to level up at night until it loves you
thunder stone, water stone, and fire stone just like in every other game... But if you want Umbreon or Espeon they evolve with love Umbreon(night), Espion(day)
just goto celestic town, and with eevee in your party, travel up and down for about 2 hours, then at night make it level up.
Umbreon-High Friendship 8:00pm-3:59am Espeon-High Friendship 4:00am-7:59pm
Espeon and Umbreon cannot be obtained in Leafgreen because no in game clock feature exists so you will need to trade one from a game that does feature this like Ruby and Sapphire.
id have to say either glaceon,umbreon,or jolteon
the best ones are Espeon Umbreon Glaceon Leafyeon and Vaporeon
umbreon
you have to evolve evee with max friendship during the day
trian in day
