I Need Selene Team Building Feedback?

Selene is a Kanto native who is feeling homesick, her Pikachu is her last real connection to her home. Her Pokemon Are Decidueye, Pikachu, Hawlucha, Naganadel, Lycanrock (Dusk Form) and Alolan Sandslash. Is this a good team or should I include some others? I had the idea to include either a Greninja (with Battle Bond) or Blaziken, opening up the opportunity for Mega Evolution later down the line. If those don't work do you have any suggestions?
