Okay, first off, You might want a good 4 of your pokemon to know Baton pass, now to the individuals.
Gliscor - You put Ev's in his Attack, yet he has no Attacking moves... I would take those out, or replace Agility with Earthquake.
Ninjask - Hardy nature? Careful is better here, moveset's fine, just make sure to make him your lead.
Togekiss - I'm not a huge fan of your set, but its OK. Just make sure to change that ability, you made it hustle, it needs to be serene grace.
Gyarados - Dragon Tail? If you're not using D-dance, ( I see why with baton passing ) Atleast use Body Slam, to be a bit harder hitting that Ice fang on Other Gyaradoses.
Garchomp - first off, 252 in Atk and spd, and 4 in hp. Secondly, Give him Dragon Claw over outrage here, so he can actually stay in after you set up your baton passes.
Ramphardos - Needs to go. Sub for....
Smeargle - You can't have a baton passing team without one! Well, you can, but he's good here.
Use this as his set.
Shift Gear - Its like a hyped up D-dance
Spore - Obvious use
Substitute - More obviousness
Baton Pass - Its what the team is based around.
Ev's in Hp and Speed, then you should be good,
Also beware that a good Physical Wall with Iron Defense, could easily smoke your team.
