Changes you should make, in my opinion:
Scolipede @Black Sludge
Nature: Timid
Ability: Speed Boost
EVs: 252 Spe / 248HP / 8SpD
Moves: Substitute, Protect/Spore, Swords Dance, Baton Pass
Talonflame @Sharp Beak
Nature: Jolly
Ability: Gale Wings
EVs: 4 HP / 252 Spe / 252 Atk
Moves: Brave Bird, Flare Blitz, Roost, Tailwind
Greninja @Life Orb
Nature: Jolly
Ability: Protean
EVs: 252 Spe / 252 SpA / 4 Atk
Moves: Hydro Pump, Ice Beam, Dark Pulse, U-Turn
1. Scolipede can't learn Spore. That above set is best suited for dedicated Baton Pass teams. Scolipede forces switches sometimes, so it does get a few opportunities to lay down Spikes, then Baton Pass out of there.
2. Talonflame needs an Adamant nature to make its Brave Birds hit as hard as possible. Jolly is also redundant with Gale Wings.
3. Jolly lowers Greninja's Special Attack, its main attacking stat.
