However, Greninja isn't like Lucario in that he doesn't have Aura. I believe Aura is one of the main reasons Lucario stayed, and ultimately Greninja doesn't really bring anything new to the party. We already have a boatload of Pokemon reps, so I think it would be best to cut Greninja to make room for a current generation Pokemon.
