Okay, here's my current team. Please don't try and change the natures of the Legendaries, I can't get another one without going through a lot of work. Also, don't include Some TMs such as Earthquake and Calm Mind Especially because so many Latios's and other Pokemon have a nessesity to know them.
Groudon, Impish, White Herb
Rock Slide, Earthquake, Overheat, Swords Dance
Charizard, Sassy, Salac Berry
Fly, Earthquake, Blast Burn, Swords Dance
Lugia, Quiet, Leftovers
Psychic, Thunderbolt, Surf, Calm Mind
Metagross, Adamant, Choice Band
Shadow Ball, Sludge Bomb, Meteor Mash, Eathquake
Snorlax, Adamant, Leftovers
Brick Break, Shadow Ball, Body Slam, Curse
Latios, Naive, Soul Dew
Dragon Claw, Psychic, Thunderbolt, Ice Beam
I'm pretty sure that you can figure out how this team works. Anyway, many have said that my team is majorly weak against an Ice and Water type such as Walrein and Lapras, so I added in Snorlax in hopes to beat the Ice and Water types out there. The other members of my team are weak to the same types (Ice, Water, Ghost.) If you have any suggestions for different pokemon, list them and their movesets with items. Thanks.
