Good idea if you have Pokemon Box: Ruby and Sapphire and a GBA to Gamecube Link Cable for a good cheat. Get anyone you want like Kyogre for instance and put it on to Pokemon Box with the Link Cable pack. Then start your game again, choose your starter and put them back on. Now you can get 2 Kyogre's and a Lv 45 at least at the start of the game! I'm pretty sure this works. Sorry if it didn't. Thanks for asking, James B
It depends in which game. If Fire Red/Leaf Green, the Gym Leader is Giovanni, and he used Ground-type. Water, grass,and Ice would be the best things to use in this, and maybe some Flying, as they can't be touched by Ground attacks. If it's for Ruby/Sapphire/Emerald, the Gym Leader is a Water/Ice type, so Electric and Grass type would be best. For Diamond/Pearl, the last Gym Leader uses Electric-type Pokemon, so Ground would have the advantage here.
