I'm going to be breeding a Jolteon soon, Timid, most likely Choice Specs. By the looks of it though, I should be able to make a Timid Eevee that fits any of the common move sets.
My questions, though, are:
Hidden Power: Grass or Ice?
Are there any Egg Moves I should breed? Either for Jolteon or for the next point:
Is a Timid nature ideal for any of the other Eevee evolutions?
Ice for sure. A whole mess of Dragons like to switch into Jolteon. I wouldn't breed any egg moves for it. HP Ice, Discharge/Thunderbolt, SignalBeam, and Substitute are enough. I wouldn't use Choice Specs on Jolteon. It's too iffy since it's too easy to switch onto a Choice Jolteon. I would also go Modest because what other Pokemon is going to outrun Jolteon? Very few so Modest is more useful.
