Most likely I will sound like a noob, but I have a simple question since I am not much experienced with baton pass.
Isn't Scoliopede the only reason why baton pass is an insanely accessable stragety now compare to the previous generations?
When that is true, than the only way to really nerf baton pass chains by limiting it to 1 or to stop Scoliopede being able to work in baton pass dedicated teams by banning it or not allow it being used with Baton Pass.
Since it's introduction, Baton Passing has always had a little niche in the metagame. Scolipede's access to Speed Boost spiked the usage of Baton Pass, but isn't really what makes a Baton Pass team. Nerfing it down to one Baton Pass is pretty stupid. Some teams will get a high boost on a single Pokemon, and Baton Pass that sole boosting around their team, and these would get shut down entirely. Baton Pass in general would also be next to completely pointless, and knocking multiple Pokemon down to lower tiers.
The Best Baton Passers :3
Scolipede - Speed Boost, Swords Dance, Iron Defense
Ninjask - Speed Boost, Swords Dance
Mawile - Swords Dance, Iron Defense
Mew - Swords Dance, Calm Mind, Iron Defense, Agility, Nasty Plot, Amnesia, exc...
Celebi - Calm Mind, Nasty Plot
Scyther / Scizor - Swords Dance, Agility, Iron Defense
Gligar / Gliscor - Swords Dance, Rock Polish
Combusken / Blaziken - Speed Boost, Swords Dance
Medicham - Swords Dance, Acupressure, Bulk Up
Volbeat - Tail Glow
Absol - Swords Dance, Agility
Durant - Swords Dance, Iron Defense
Halucha - Swords Dance, Agility
Keep in mind that these are not all viable threats alone. Most of these need to have 2-4 other Baton Passers alongside to give them bulk.
