I've been using Masuda to try to get a shiny Eevee, so I have a ton of regular ones, and since I've been busy with exams I decided to spam happiness on some of them. These Eevees can be traded as is, as a level 2 Umbreon/Espeon, level 5-6 Leafeon/Glaceon, or level 1 Flareon/Jolteon/Vaporeon.
Maxed happiness: Hardy, Serious (x2), Relaxed, Careful
Maxed happiness, with Curse: Relaxed, Serious, Calm, Brave, Adamant
With Curse: Quiet, Impish, Hasty, Sassy, Lonely, Brave (female), Mild
Normal: Serious (x3), Sassy, Naive (x2), Lonely, Docile, Mild, Naughty
Normal (female): Impish, Lax, Hasty
Regular Eevees are basically free (if you've got an interesting item that's cool). For the evolutions, offer away!
