Ninjask

Ninjask is super fast and provides even more speed with its Speed Boost ability, and supports teams thanks to Baton Pass + a x4 SR weakness. On standard teams, Ninjask can provide extra speed to mons that can appreciate it like Goth, Hawlucha, Rapidash-Galar, and more. With Court Change in mind, it works as a 6th mon for its x4 SR weakness and huge speed to help guarantee a Sub and Protect to put it in range of a single SR switch in KO. It even has Sandstorm which it's vulnerable to so it can hurt itself further.
