Here's a better one than the one I made earlier:
Espeon @ Leftovers
Ability: Magic Bounce
EVs: 252 HP / 156 Def / 100 Spe
Calm Nature
- Calm Mind
- Stored Power
- Dazzling Gleam
- Baton Pass
So, Calm Mind is good to boost Stored Power and for Baton Passing.
Stored Power for STAB and because it gets boosted by Calm Mind
Dazzling Gleam, because it's a move that doesn't need to be boosted and for type coverage.
Baton Pass for after you use Calm Mind to hand your boosted stats to another Pokémon.
