Replaying Crystal, trying to decide on my team. So far have :
Typhlosion
Donphan
Ursaring
Poliwrath
Victreebel

Just trying to pick a flyer. Don't want type overlap so no regional birds or Noctowl, no Crobat. Xatu is just bad, my only real options are Skarmory or Dragonite. Both are very late game, however, unlike the rest of my team who I've caught before Falkner.

Any tips? I'd happily switch out some of the above for a more diverse team.
