What to evolve a 100% eevee into and Last Resort?
Hi! I caught a 100% eevee but i have no idea what to evolve it into. Is there any Eeveelution more useful than the rest at present? Should i save it for future evolutions (maybe Sylveon for the fairy typing)? Besides that, should i evolve it during the community day window? Is Last Resort really worth it? I haven't used the naming trick yet so i can use it to get any eeveelution avaible (Leafleon and Glaceon seem to not be in the game yet).
Any help.you can give me with a little explanation would be highly appreciated, thank you!

Save it for Glaceon, its going to be very useful if Rayquaza and Groudon come back after gen IV, and ice covers a good number of types (dragon, flying, ground, grass) and having high attack stats with some decent bulk to make it have longevity
Sylveon is not worth saving it for, that is at closest, a year and a half to two years away, glaceon is a much better option, namely as glaceon is much closer, is an ice type that actually has good stats that dont leave massive trade offs (unlike jynx thats massive DPS, but frail as heck, or cloyster, much tankier, but less DPS,)meanwhile sylveon likely will be outclassed by Gardevoir and Togekiss as both have better offensive stats, and likely better defensive ones as well
