So I know very little about Pokemon ever since I quit playing them back in Gen 2. My friends have gotten me into some Minecraft Pokemon mod, and I need advice. I want to make a team of all Eevees, for reasons.

Assume that all versions of Eevee are available except for Slyveon. Out of those 7, which 6 would you keep? Which 5 would you keep? I'm trying to get rid of the least practical/used one. I imagine Glaceon and Vaporeon have a lot of crossover right?
