Battle Frontier Team

[wilt_me]

After defeating the Elite Four in Pokemon Emerald, we usually proceed to the Battle Frontier to sharpen our skills in battling.
So the point is to make a team of 4 (or 3, if you prefer single battle, but not the case for me though) and get the gold symbols. What kind of teams are considered to be good?

Please rate and comment on mine:
1.
Latios, Level 100, Rash, Leftovers
Dragon Claw
Shadow Ball
Psychic(max PP)
Luster Purge
Maximized HP, Sp Attack, Sp Defense, Defense and Speed using vitamins.

2.
Tyranitar, Level 100, I couldn't remember his nature, none yet (suggestion needed)
Earthquake(very nice since he won't hit my 1 and 3)
Crunch
Rock Slide(max PP)
Hyper Beam
Maximized Sp Attack, Sp Defense, Attack, Defense and Speed using vitamins.

3.
Zapdos, Level 100, Docile, King's Rock
Light Screen
Charge
Thunder(max PP)
Drill Peck
Maximized HP, Sp Attack, Sp Defense, Attack and Speed using vitamins.

4.
Heracross, Level 100, Quirky, Focus Band
Break Brick
Endure
Mega Horn(max PP)
Reversal(I use endure when HP is low, so this move will be extremely powerful>.<)
Maximized HP, Sp Defense, Attack, Defense and Speed using vitamins.

To be honest, I use Gameshark on Vba, but please don't mind it and just give me some advice. Thanks!

Moving to in-game team help forum. idk if this meets the standards, but it should be okay.

It's a great sweeper team overall. But It doesn't have much support or defense Poeks that could back them up. But in a good battle this team should be able to swipe the plate clean.

It has to be 3, if you want to get symbols. Sorry.

Latios:

Dragon Claw / Psychic / Surf / Thunderbolt would provide pretty good coverage, or you could give it Calm Mind, which would make it beastly.
