Instructions
Study Claire's team and pay attention to the type of Pokemon and their strength levels. Claire's team consists of two Dragonairs at level 38, a Gyrados at level 38 and a Kingdra at level 41. Ensure that your Pokemon are at least a level 38 to compete in strength with Claire's team.
Start the battle with Claire's two Dragonair Pokemon by using Lapras. Capture a Lapras in the Union Cave basement on a Friday. Claire's Dragonairs are weak to ice attacks, so use Lapros' Hail attacks and Ice Beam attacks to defeat the Dragonairs.
Battle Gyrados with Ampharos since Gyrados is weak to electronic attacks. Acquire Ampharos by evolving a Mareep into a Flaafy; then evolve a Flaafy into Ampharos. Use Thunder or Thunder Punch attacks.
Battle Kingdra with your Dragonair Pokemon. Kingdra is vulnerable to dragon attacks. Find a Dragonair by exploring and fishing in the cave behind the Blackthorn gym. Use the Dragon Pulse attack.
