What Pokemon do you need to beat lance?

What you need is a feraligatr.and then a gyrarados at level 45 or higher and then at least 2 ice Pokemon at level 45 or higher and then you should get a dratini and evolve it into a dragonair and then evolve it into a dragonite which is at level 55 and one of the legendery Pokemon like entei HO-OH or raikou. That is one of the best ways to beat lance well that's how i beat him.
