Baton Pass is probably the most unique and interesting move in Pokemon. Unfortunately, it sees very little usage in OU right now. Nevertheless, my baton pass team has been performing decently well on the PS ladders (I'm currently 42-19). Of course, this is far from perfect and any help you can give would be appreciated. Without further ado, here's the team!
Ninjask @ Leftovers
Trait: Speed Boost
EVs:252 HP/- Spa/4 Spd/252+ Spe
-Substitute
-Protect
-Baton Pass
-Swords Dance
Ninjask is usually my lead, and for good reason. Unless I'm facing a Prankster with Taunt, he's guaranteed to pass at least +1 Spe. Typically though, I can get up to +6 Spe if I so choose, as, without any form of priority or the move Taunt, most Pokemon find it extremely difficult to stop Ninjask from alternating Substitute and Protect to stall for speed boosts. Once I am satisfied with my speed (it's nice to have a substitute up as well) I pass to the Pokemon that I believe best handles the current threat. Typically, this will be Espeon, Vaporeon, or Mew.
Espeon @ Leftovers
Trait: Magic Bounce
EVs: 252 Hp/- Atk/252+ Def/4 Spd
-Calm Mind
-Baton Pass
-Morning Sun
-Stored Power
This is hands down the most important Pokemon on my team. Once I get a few speed boosts, it turns every single Baton Pass on every one of my Pokemon into a pseudo-Magic Coat. Also, it is probably the most terrifying receiver in the game: With a decent number of boosts from other Pokemon and after 1 Calm Mind, it will OHKO pretty much anything other than Blissey or a Dark Type. Recovery is nice also, even if it does take the form of Morning Sun. However, Espeon's main use is definitely its ability: The importance of Magic Bounce to this team cannot be overstated. Magic Bounce deals with Roar, Taunt, Encore, Torment, etc. These are all common or not uncommon moves that can devastate an unprepared Baton Pass team.
Smeargle @ Focus Sash
Trait: Own Tempo
EVs 252 HP/- Atk/4 Spd/252+ Spe
-Spore
-Baton Pass
-Ingrain
-Substitute
Smeargle's main use on this team is that it is the only Pokemon that gets both Spore and Baton Pass. If my opponent tries to set up alongside me with a stat booster such as Calm Mind Celebi (although this works against many stat boosters, especially those without priority), I can Baton Pass to Smeargle, take a hit if need be with Focus Sash, then either Baton Pass out or set up Ingrain, depending on the situation. Ingrain is a useful move, it allows me to beat Roar when Espeon is low on health and mispredicting could be fatal. It also allows me to beat damaging phazing moves when my current Pokemon does not have Substitute. Substitute is just a useful move that allows Smeargle to dodge status. It is also another great thing for Smeargle to pass if it has a free turn due to sleep.
Vaporeon @ Leftovers
Trait: Water Absorb
EVs: 252 Hp/- Atk/252+ Def/4 Spd
-Acid Armor
-Wish
-Scald
-Baton Pass
Vaporeon is my defense booster. It is also one of three Pokemon with an attacking move, the other two being Scizor and Espeon. Typically, Vaporeon will end up attacking with Scald earlier in the game. Its most common Scald target is definitely Scizor, as the burn usually proves deadly and Scald hits for decent damage as well. Wish is subpar recovery, but Vaporeon lacks a better option. I considered Protect over Scald, but Vaporeon was easy set up bait for too many things. All in all, Vaporeon provides a valuable role on this team: Without it, physical attackers, such as Scizor and Conkeldurr, would completely dominate this team.
Mew @ Leftovers
Trait: Synchronize
EVs: 252 Hp/- Atk/4 Def/252+ Spd
-Amnesia
-Substitute
-Baton Pass
-Roost
Mew is an incredibly reliable Spd booster, and is also my most reliable Substitute producer. A large part of this reliability is due to Roost; it enables Mew produce infinite (well, 16) Substitutes once they are 2HKO'd. It also allows me to reach x4 Spd fairly easily, although this isn't always necessary. There isn't really much to say about Mew, it's fairly self-explanatory.
Scizor @ Leftovers
Trait: Technician
EVs: 252 Hp/4 Atk/252+ Def/- Spa
-Bug Bite
-Swords Dance
-Roost
-Baton Pass
Scizor is my only physical attacker. Its Bug stab and high physical bulk also pairs wonderfully with Espeon's Psychic stab and low physical bulk. Roost + Speed boosts allow it to win vs other Scizor, especially after a Def boost or two. I usually Baton Pass to Scizor only with a Sub up if there's a risk of it getting burned or hit with a Fire attack, as both those things are extremely difficult for Scizor to deal with. Scizor's bulk, good defensive typing, and ability to set up in the face of attacking pressure make it a valuable member of this team.
