Noctowl and Torterra are not good for the next gym, the Darmanitan is already a huge step forward and maybe an Aggron(from the railnet's other outcome you headbut the pole for aron) for Ice types
I would NOT use the Scrafty. It's a powerfull Pokémon, true. But the leader after Luna eats Dark Types as a snack. I sugest you would get a decent Bug Type.
I have a feeling there wil be a side quest for it later on. Though(like every1 said already) nothing is sure yet, only that an other Team Metoer member has his wife laying in a grave there...
