Pokémon Emerald Tips

Easiest Battle frontier wins
When you you are in the battle frontier bring a trio of lv. 50 normal type pokemon with all different attacks. (This is best for the battle dome events, and make sure that you keep/learn BODY SLAM if you can, because it's a strong attack to have). And any battle points you get, spend on medicine and bonuses like HP UP for your pokemon to make winning alot easier next time.
