Flame wheel on Raticate is my first through too. A more mundane one, Game Boy-era screens. Mostly Reflect being surprisingly generic, I know most birds, fire, and electric types could learn it, you could get Light Screen on Machamp or Venusaur through breeding but I have not seen how deep that one goes.
