Will, after seeing all this, I think I'll:
- keep the first set (but maybe add more description on salac, it isn't that bad).
- rework the second set.
- create a standard trick set. Although something like alakazam outclasses it, espeon has kinda more bulk. Besides, this set can used somewhere were alakazam can't be. As of trick and baton pass, I don't think it's really effective. Are you going to trick something, then CM up to baton pass? or is it just for scouting? I don't really see it's effectiveness. I'll try testing it, though.
- I think I'll try a supporter set, something like a wishpasser or so, even if it's speed is high.
As far as the flame orb thing is concerned, I can't find it useful at all. Inflicting yourself with burn isn't really good, especially with SR, spikes, and sandstorm everywhere. I wouldn't say it will work.
Anyways, I'll start testing now, and update when done.
Thanks for your time.
EDIT: I'm done with this for now.

<p>Baton Passing Espeon, or "EspyJump" makes a return from ADV. Once you have Espeon in, you should lead with either Baton Pass or Substitute, so you can scout what your opponent is sending in to counter her. If you have a Sub set up as a slower opponent comes in, you can freely pass it to an appropriate counter. When facing a weaker special attacker you can begin boosting with Calm Mind, creating an unbreakable Substitute before passing to a sweeper. You have many options to choose from for a Baton Pass target, but the likes of Zapdos, Porygon-Z, Lucario and Empoleon are all fine choices, especially if they are carrying Agility.</p>
<p>Given the prevalence of Tyranitar and to a lesser extent, Hippowdon and Abomasnow, you may want to carry some weather support on your team if you are planning to use this set. Damaging weather hinders this Espeon's ability to tank special hits and repeatedly use Substitute, so a Sunny Day or Rain Dance user would provide welcome respite from this.</p>
<p>Replacing Leftovers with a Salac Berry can prove useful. For example, if you use Sub as Weavile comes in, you are free to Sub two more times to activate the boost, after which you will be left with an intact Sub and Speed higher than that of Weavile. This allows Espeon to safely Baton Pass the Sub and Salac boost, or use Calm Mind before passing a +1 boost in Speed, Special Attack and Special Defense to a sweeper.</p>

<p>This is a more attack minded set that makes greater use of Espeon's excellent base 130 Special Attack. Psychic is your main STAB attack, while Hidden Power Fighting OHKOs Weavile and 2HKOs Tyranitar. Fake Tears can prove useful for your team if it has a few special attackers to take advantage of it if Espeon is forced out, and can also be helpful at causing switches if you have Stealth Rock and/or Spikes up. Calm Mind, on the other hand, can boost Espeon's already high Special Attack and mediocre Special Defense to further support her at sweeping by herself. Although you're not passing anything, Baton Pass is recommended in case you're met with something like Metagross or Spiritomb, so you can simply Baton Pass out to avoid getting hit with Pursuit. Alternatively, you can use Signal Beam to hit Espeon's fellow Psychic-types, who otherwise completely wall this set.</p>

<p>Espeon now learns Trick, and can effectively utilize it along with its high base Special Attack and Speed. The setup is pretty simple: Come in on something that is scared by Espeon, and act accordingly. If you know a Blissey is going to pop up, go ahead and use Trick. If you know a frail sweeper is likely to switch in, attack with STAB psychic or super effective Hidden Power. If you are unsure of what to do, use Baton Pass, and then safely send in a pokemon that can counter it. If you don't like Baton Pass here, you can use Signal Beam instead to hit other psychic types. Grass Knot is also an option here if you have no other way to deal with Swampert.</p>
<p>You can also use a Choice Scarf on this set. If you do, go with an EV spread of 112 HP / 252 SpA / 144 Spe. This spread hits a magic number and gives you a speed of 480 with a Choice Scarf, making you faster than modest, max speed Choice Scarf Gengar by 2 points. If you do want to outspeed max speed, modest Choice Scarf Alakazam, go with 36 HP / 252 SpA / 220 Spe.</p>
[Other Options]
<p>Espeon's most viable attacks have been listed. She learns a few good support options like Wish, Charm and Reflect, but it's hard to find a slot for them. If you have some Sunny Day support, you're free to try using Morning Sun. Beware of Tyranitar, though.</p>
[EVs]
<p>For the Baton Pass set, you should focus on HP, Special Defense and Speed. The defensive EVs allow Espeon to tank special attacks while setting up and the Speed EVs help to Baton Pass before taking a hit. 196 HP EVs hits 320, allowing for optimal recovery from Leftovers. Timid with 216 EVs will outrun Mismagius, while 240 EVs will let you outspeed Infernape. You can also max out speed if you want to try your luck against Gengar. Any remaining EVs should go in Special Defense.</p>
<p>The EVs of the Fake Tears set should be focused on Special Attack and Speed—maxing out both is fine. If you would like a little more HP, then drop her Speed to 334, 340 or 347 and use a Timid nature. As far as the Trick set is concerned, maxing out Special Attack and Speed with a timid nature is just fine.</p>
[Opinion]
<p>Espeon still remains as a useful Baton Passer, and is one of the more usable Psychics—a combination of Baton Pass and high Speed makes it almost impossible for opponents to smack her with Pursuit. Although she is quite easy to wall, her strength as a Baton Passer makes her a valuable asset to have on your side.</p>
[Counters]
<p>The trouble with countering Espeon is that most "counters" are usually met with an immediate Baton Pass to safety, which even nullifies Pursuit. Still, on her own Espeon is countered by Tyranitar, barring Hidden Power Fighting. Tyranitar also stirs up Sandstorm, which severely limits the effectiveness of the Baton Pass set, as it nullifies Leftovers recovery. Metagross shrugs off Espeon's attacks and also has Clear Body to screw up Fake Tears. Weavile is OHKOed by Hidden Power Fighting, but if it gets in safely then Espeon will fall, as the icy weasel is one of the few Pokémon with Pursuit who outspeeds Espeon. Spiritomb is a fine choice as it is immune to both Psychic and Hidden Power Fighting, and it has Sucker Punch and Pursuit. Beware of Trick, though.</p>
<p>Blissey takes Espeon's attacks with ease, although she can be beaten with Fake Tears. The Trick set can severely hinder her, too, so one must practice caution when switching her in.</p>
And that's basically it. Please notify me of any mistakes you can find. I coudln't think of any more sets, but if you have any ideas, please post them here.
Thanks for your time!
