Don't use Physical Attack on Volcarona because it has only has 60 base Physical Attack and it has 130 base Special Attack, so every move on Volcarona must be Special Attack. Don't use Solar Beam, it waste turn and it didn't give much coverage as other move, if you still want a Grass type move, then Hidden Power Grass is a lot better. Don't use Flamethrower on Volcarona because Fiery Dance is a lot better than Flamethrower. Fiery Dance only have about 20 base power less than Flamethrower (if count STAB) and it has 50% to gain Special Attack which means after one Special Attack boost from Fiery Dance it will have more power then Flamethrower. The only other Fire type move to use on Volcarona if you don't use Fiery Dance is Fire Blast because it has high base power (or Heat Wave if you are playing Double or Triple Battle).
