Okay, let me explain something:
If he's talking about Generation III, then yes, hyper beam is physical because just about
all normal type moves were considered physical. However...
What's recommended for Gen III is a special Flygon. Let me explain why:
Flygon@Choice Specs(I think they had this in Gen III?)
Mild Nature
- Earthquake(For STAB, of course. You can't forget the awesomeness and strength that is Earthquake when combined with stab
- Dragon Claw(Dragon Claw is considered a special move in Gen III, hence is also why I chose Mild for best stab)
- Flamethrower(Not only would this be beneficial to the nature, but also to pokemon like skarmory and other pokemon that resist EQ and Dragon Claw)
- Rock slide (For the flyers and ice types that get in the way)
Though the choice specs is BEST used when considering Dragon Claw. Otherwise, just stick with Leftovers or something of that sort. D:
But I really hope this is Emerald you're playing, so you could regain Earthquake and the such after you've used them.
