Jolteon: Rash Nature
Vaporeon: Bold Nature
I just wanted some opinions... I kind of want to use the Eeveelutions, just because Eevee is too much of a gangster to ignore, but I'm willing to consider ANY feedback and suggested replacements or natures... I haven't actually started EV training yet, because I wanted opinions.
[Also, I don't much care for the fifth gen pokemon... So try not to include them if you can.]
