Hi there! Baton Pass is a very important strategy in Nat Dex AG, however it's not always used as an entire team. Such teams are viable (and are usually randomly bought to and win at least 1 game every tour), however I wanted to quickly mention a couple of different styles of BP besides FullPass.
Baton Pass Calyrex
Calyrex-Shadow @ Leftovers/Ghostium Z/Life Orb/Buginium Z/Focus Sash
Ability: As One (Spectrier)
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Astral Barrage
- Baton Pass
- Substitute/Psyshock/Draining Kiss/Pollen Puff
Behold, the defining set of AG. This set allows Calyrex-S to abuse its usual switch-ins in bulky Yveltal and Arceus-Dark by Baton Passing Nasty Plot boosts and/or potential Subs too. Many of Nat Dex's most dangerous breakers are essentially unwallable with a free +2 SpA and entry on a relatively passive Dark type to boot. Baton Pass additionally allows for escaping potential Pursuit trapping from the occasional Tyranitar. Leftovers is typical with Sub to allow Calyrex the ability to set more Subs and resist residual damage. Ghostium is an alternative nuke that allows Calyrex to kickstart a snowball sweep/get a free kill and +1 boost against a foe that expected to take an unboosted hit and force it out, like (admittedly rare now) max/max Zacian-C. Psyshock gives a secondary STAB to make Calyrex a better solo sweeper against Normal types like Blissey. LO+Draining Kiss can be used to add longevity and OHKO bulky Yveltal with +2 Max Starfall. Pollen Puff+Buginum gives an alternative nuke that pastes many common Dark-types at +2. Sash together with decent hazard control lets Caly-S beat things 1v1/BP in front of things it shouldn't.
You can essentially almost throw this set onto any team with another special/mixed breaker that abuses Caly's normal checks (Mixed Mega Ray, GeoXern, LO YGod, Eternatus etc etc). The only consideration is whether your team would appreciate a different Calyrex set more really.
SmashPass
Smeargle @ Focus Sash
Ability: Moody/Own Tempo
EVs: 4 HP / 252 Def / 252 Spe
Jolly Nature
- Baton Pass
- Shell Smash
- Spore
- Taunt/Substitute
This set is pretty self-explanatory. Moody can screw you sometimes so Own Tempo is a valid choice, but Moody can also break the game. Best paired with HO staples like Webs Smeargle/other suicide leads+3-4 breakers/sweepers. Pretty much anything on the receiving end wins with all those boosts, but Mega Ray stands out due to Extreme Speed access, fitting well on Webs even if it doesn't receive boosts and naturally high stats to boost.
(there is also Magearna, but it's basically budget Caly-GG)
FullPass
FullPass (using 6 Pokemon with Baton Pass to pass around stat boosts until you win) remains extremely efficient at match-up fishing non-Ditto teams in Gen 8. Thanks to no Evasion Clause in AG, Baton Passing Minimise allows mons to get plenty of free turns to boost. I don't have any teams of this to hand (and I suck lol) but here's a pre DLC-2 replay so you know what you're looking for:

Checklist For Good FullPass:
Espeon (STAB Stored Power+Magic Guard)
Smeargle (Normal type+Ingrain+Moody)
Way to raise evasion
Speed-boosting lead
Counterplay to Haze, Roar and Perish Song (Soundproof and/or Taunt)
Yveltal check
Zacian check
Caly-GG check
GeoXern check (by "check", I don't mean it should have to beat any of these 1v1, just has to be able to defensively boost and/or stall Dyna in front of them until they are no longer a threat)
Just in general be careful of Dyna'ed mons, Max Moves always hit and you can't really Dmax back. Your best bet is acquiring a Speed advantage and spamming Sub until Dyna wears off. Also, you see a Ditto, you either keep up a Sub at all costs or click X.
So that's a quick (and slightly bad) overview of Baton Pass in Nat Dex AG! Just remember Calyrex is OP and you'll be fine! (For teams, I recommend checking out the commencement threads of big tours like AGPL III, they usually have a few teamdumps at the end of them so you can pick a couple you like, just make sure you pick a Nat Dex one lol.)
