What is the best battle team for the battle pike in Pokemon emerald?

you and me

Now, GastlyGhost will give you a good answer with what Pokemon to use. I used a Magneton; Lock-on, Zap Cannon, Swift, and Spark. Its STeel type makes it resistant to Pike Queen Lucy's Seviper Poison type moves, and Shuckle's Toxic and Sandstorm. Its Electric type also was AWESOME on her Milotic. I also had to take two pack ups, a Golduck; Strength, Disable, Fury Swipes, and Hydro Pump. It had fainted before Lucy but it would do great against Shuckles Rock type, and resistant to Milotic's Water type moves. Then my Metagross; Take down, Scary face, Persuit, and Psychic. Steel is resistant to Shuckle's Sandstorm and Toxic as well as Seviper. Its Psychic moves would dominate Seviper. I hope that this helps. I used these Pokemon and I won without any held items! Good Luck.
