If your base is an easy 3-star for a GoWiPe you might consider using archers, since PEKKAs hit slow, which will make them waste valuable time on your troops.
Dragons, though, are always a great choice because of their large hitpoints and splash damage. It's basically a flying wizard that will not be one-shot.
