How do you get an shedinja?

Answer 1

You level up a Nincada to level 20,

yet at the same time having an empty space in your team (Shedinja will fill this space.)

and having a spare pokeball (only a pokeball, not a great ultra, or other kinds.)

And your Nincada will evolve into Ninjask and a Shedinja will fill up that empty space.

Wll you can have a other type of ball what I mean is Poke Great or Ultra Works the other types like Nest Love etc wont work I have my shedinja in a(n) ultra ball

Answer 2

To get a Shedinja in Pokémon games, you need to have a Pokémon with the ability Wonder Guard and an empty slot in your party when evolving Nincada into Ninjask. When Nincada evolves into Ninjask, Shedinja will appear in your party if all the conditions are met.
