I'm playing pokemon Colosuum, but I ain't sure what moves to have my flygon. I think flamethower would be useful, but I don't know what to change on my pokemon, a friend said to swing dragonbreath for flamethower, but, it's kidda ruins the pokemon that it has no move that stab for it's type.
Flygon is impish nature, knows: crunch, giga drain, steel wing, and dragonbreath. If it is better, what move sould I make my pokemon forget for flamethower.
