Since Lance has Dragon-type Pokemon, Glaceon will be recommended, for Dragon-type Pokemon are weak against Ice-type attacks. Unfortunately, some of his Dragon-type have Fire-type attacks, which will come to your disadvantage for defense.
Lance has dragon types. Your best bet is to use ice types because they have an advantage against dragon types. Another thing to try is using dragon types but you would be at a disadantage as well.
Most of his Pokemon are Dragon Types, so bring an Ice move. Don't rely on a Gyaradose with Ice fang though, unfortunately, his Dragonite knows Thunder. Also, bring a Pokemon who knows Thunderbolt, to knock out his Gyaradose.
Any ice Pokemon
I might say Articuno if you don't have anything with ice moves because you'll need it against lance. Or Zapdos to help defeat Lorlei with her water/ice types. Moltres in my opinion is the worst out of the 3
Ice type Pokemon can easily defeat lance's Pokemon also for his gyrados and aerodactyl you can use an electric type.
In any case, I would choose Totodile. Totodile is the strongest of all the starters, considering his stats, and can learn ice moves, which are extremely useful against Lance's dragons. If I am correct, then Lance will still be the Champ, as in Crystal, Gold and Silver?
Not a very precise question, but I'll do my best :P. The Elite four are 4 very powerful trainers that you have to defeat to reach the champion of the Pokemon League. However, you must have 8 badges before you can challenge them. They are as follows, Lorelei the Ice Pokemon trainer, Bruno the fighting Pokemon trainer, Agatha the ghost Pokemon trainer and Lance the dragon master. I would suggest you use an Electric Pokemon and a Fire Pokemon for Lorelei, a Flying/Psychic and Water Pokemon against Bruno, a Psychic Pokemon or one that knows Dark Type attacks against Agatha and an Electric, an Ice and a Water Type against Lance.
For his Dragonites (x3), have Ice-Type Pokemon at hand. For Charizard, have a Water-Type Pokemon. For his Gyarados, have a Electric-Type Pokemon. For his Aerodactyl, have a Water-Type as well. The 2nd time you face him: Use Ice or Electric Moves or Pokemon against his Salamence. Use Ice or Water Moves or Pokemon against his Garchomp. Use Ice or Electric Moves or Pokemon against his Altaria. Otherwise, he has a Dragonite, Charizard, and Gyarados. Just read above to know how to handle them.
depends on Pokemon. against lorilei my zapdos deals to dewgong, cloyster and lapras but its my charizard that's good against the ice type.
electric, ice, rock
All you have to do is train your Pokemon or have a Pokemon with a good ice move
