Oh! Goodness, you should! We haven't used it in battle yet, but I have heard it's supposed to be an excellent boost in power if you do - and some Pokemon change their types! Dinah gains the Fairy type, for instance - I don't know about Lucario, but if your Danny is willing to give it a try, then by all means, go for it!

[Dinah just shrugs. She had a lot of fun with the experience, and her trainer had fun, and that's what matters to her - and also they're in this cool new place! That's already so much better than votes!]
