Ninjask

Ninjask has a successful niche of utilizing Baton Pass; the secret lies in Ninjask's ability, Speed Boost, which raises its Speed every turn, and when this is Baton Passed to a teammate in succession, it can pull off a threatening sweep. Holding the title of the fastest unboosted Pokemon in the tier, Ninjask fits perfectly onto dedicated Baton Pass teams as a Pokemon that can rack up Speed boosts with Protect and Substitute easily. While its frailness and 4x weakness to Stealth Rock prevent Ninjask from staying on the field for very long, it will always be a coveted member of a team in need of speed.
