App ally and villain pack question

By Eronenris, in Legends of the Alliance

So with the app, when these allies and villains are called to play. Do we use the cards that go with these characters or does that app just tell us what to do with the characters? The reason I am wondering is, I just bought everything this game has to offer, specifically for this app. (been waiting for this since the release of this game) I just need to know when putting all this away and organizing it, if I even need to bother organizing those ally and villain pack cards into the mix.

Any help is great, thanks.
