How do beat Lance and Clair in a double battle in Heartgold? - Answers

This is really hard, and you need some really tough pokemon. Since it's a 2 vs 2 battle, I suggest a really strong electric type (I use Amparos) and something that knows Sleep powder and Leech seed (like a Venusaur). Most dragon types are secretly flying types, so they are weak to electricity. Sleep powder will save you (kind of) from a few attacks, but do this quickly, before the dragons can use any fire move. My Venusaur took a fire blast to the face ad survived, but that isn't a common thing. leech seed is the best, because it saps away life, boosts your own life, and doesn't affect the foe's status like poison powder does. For here on out, it's about tenacity and lemonades. That's really all I can say.
