In Pokemon X and Y there are battle boxes, but I may need more than 1 of those. Is there a way I could have 2, not just one?
There is only 1 battle box, but you can also use the Pokemon in your party to battle, so you can have 2 teams ready for battle at any time
Hope I helped
I'm sorry to disappoint you, but the answer is sadly no.
The Battle Box may only hold up to six Pokémon at a time, no more. It would be nice if we had two, but GameFreak just made it that way.
