[OVERALL]
Ninjask, with 160 Speed, a not bad 90 Attack and a not bad movepool, is one of the best BatonPassers in the BW Uber metagame, maybe only outclassed by Smeargle (Shift Gear) and Gorebyss (Shell Smash)
[SET]

Move 1: Baton Pass

EV: 248 HP / 160 Def / 100 Speed
[Set Comments]
- +2 Attack and +2 Speed is really helpful for most sweepers (Rayquaza, Giratina-O, Ho-Oh, Groudon etc.)
- Protect gives a free Speed boost
- With a Jolly Nature, outspeeds +1 Rayquaza (if Mild / Naughty) and Timid Scarf Kyogre
- Substitute stops Lugia trying to phaze with Dragon Tail
- Great Attack to sweep with, X-Scissor is 1HKO on most Mewtwo and Darkrai
- With this spread, can resist at unboosted Life Orb Extremespeed from Arceus
[Other Options]
- Mental Herb can be used to prevent Taunt
- Lum Berry avoids Will-O-Wisp, Thunder Wave and such
- Bug Bite can eat Lum Berries
- Hone Claws, boosting Attack and Accuracy, helps sweepers that use low-accurated moves (Stone Edge, Dragon Rush, Aqua Tail etc.)
- Metal Claw can kill foes with 1 HP for Focus Sash and give a free Attack boost, but X-Scissor is preferable
- Other offensive moves are Aerial Ace, Night Slash and Dig, but they're quite useless
[Checks and Counters]
- Thundurus is maybe the worst counter, with Prankster Taunt + Thunder Wave
- After two Stealth Rocks damage Ninjask is dead, so Rapid Spin support is absolutely necessary
- Extremekiller and can easily outspeed and score a 1HKO
- Encore (Jumpluff, Whimsicott) forces a switch
- Shadow Sneak from Giratina-O does 58% - 68%, 1HKO after Stealth Rock damage
- Minor counters are Zekrom, Groudon, Rayquaza, Lucario
[Partners]
- Rapid Spin support is a must, best partners are Forretress, Excadrill, Kabutops
- Ninjask works well in Baton Chain Teams, so Gorebyss can help passing Shell Smash or Amnesia + Iron Defense
- Groudon is a great partner: Thunder under the sun has only 50% Accuracy, so set-up Substitute is easier, and decrease the power of Water-type moves (for example, 252+ Palkia @ Lustrous Orb does only 40% - 48% with Aqua Tail)
- Baton Pass is useful especially for mixed sweepers such as Giratina-O, Palkia, Rayquaza and for set-up ones (Dragon Dance, Bulk Up)
