>>42598166Crobat isn'tan overly hard hitter but is wicked fast and gets access to Mean Look which is great for hunting Raikou and Entei, but it should be raised from hatching after getting a Zubat Egg from the Daycare. This Egg should be fathered by a Hoothoot or Noctowl that knows Hypnosis. Again, for roamer hunting.
Skarmory also isn't a hard hitter but just walls physical attackers. The drawback with it is that it is lategame unlike Crobat (Route 45 vs. Route 30/Dark Cave for Zubat)
Flygon isn't even a Flying-type and Trapinch is a postgame Safari Zone encounter.
