I need help finding the best coverage for a 3 attacks Espeon. And 4 attacks too for that matter.
Options:
Psyshock / Psychic
Shadow Ball
Grass Knot
Hidden Power Ice
Hidden Power Fire
Hidden Power Ground
Hidden Power Fighting
Picking the right HP type is really hard. Any help would be great. And please take into consideration the OU metagame when calculating coverage.
I would recommend Hidden Power Fire to get past one of the main counters to Espeon: Scizor. With Hidden Power Fire, Scizor's only hope is to use Bullet Punch, wich may not OHKO if Reflect is up or Espeon is at good health. If you have many ways to get past Scizor on your team, however, you can use Hidden Power Fighting as it help Espeon get past Tyranitar, another solid counter to her, but take care that Tyranitar can survive if it has Chople Berry.
I still recommend Hidden Power Fire, as with Psychic/Psyshock and Shadow Ball, you will have problems getting past Steels. As they are more common than Dark-types, and most Steel-types are weak to Fire but take neutral damage or are immune to Fighting and Ground, Hidden Power Fire is your only hope against them. If you are really paranoid about Dark-types or Heatran (wich is the only Steel-type in OU that doesn't fear Fire), however, use Hidden Power Fighting.
I wouldn't recommend Hidden Power Ground as Ground is the least effective type to take Steel-types, as there are many Steel-types on OU that are neutral to Ground, and many of them also carry Air Baloon, so even if you use Hidden Power Ground you may not get past Steel-types at all.
As for the choice between Psyshock and Psychic, I generally use Psyshock, as with that, Espeon can get past special walls such as Blissey and can win Calm Mind wars, not to mention that she can act as if she were a mixed sweeper. But if you fear Fighting-types that can survive an unboosted Psyshock and retaliate, such as Conkeldurr, then use Psychic.
