I know the free-space part, but in my full pokemon book it said a pokeball is needed.
Is there a specific poke ball like Great ball or Ultra ball, or can it be any poke ball?
I'm pretty sure it needs to be a Poke Ball.
Need empty space
Needs Poke Ball
Hope This Helped :D
Have a Pokeball and an empty space in your party, so when Nincada evolves into Ninjask, you will need a Pokeball to put the Shedinja in!
Hope this Helps! XD
