You, my friend, are extremely lucky
People only get this get kind of stuff on Wednesdays. Let's see what to do with your lucky Espeon
My best bet is to run a sweeper set with either Choice Scarf or Life Orb. Your Espeon has Hidden Power Dark, because it has 6ivs, but it's not really run on Psychic types.
Espeon @Life Orb/Choice Scarf
Trait: Magic Bounce
EVs: 252 SpA, 252 Spe, 4 SpD
- Shadow Ball
- Dazzling Gleam
- Signal Beam/Trick
Italics are used if you want to use the Choice Scarf set.
Hope I helped!
