I know of one strategy but its only on Dusty.
First you have to battle dusty one (1)time.
Then remember his team\Pokemon (Like if his team was Primeape,Riolu and Flygon.)
Then remember his first Pokemon,his second and so on...
(You have to see ALL his Pokemon!)
Then let Dusty defeat you on purpose.
Final step:Pick the Pokemon that have all the type advanages on his team.
Now your ready to go!I hope you win!!!
(I forgot to say that before you pick YOUR Pokemon you should take a look at his pokemons moves first,so your Pokemon wont be defeated.Oh...I forgot to say something.You MUST beat all the trainers in a singel row.Then you get Perfect Points.This will help you when dusty defeats you on purpose.If you don't do EXACTLY as it says here,then you must start the whole colosseum again.)
(Remeber:You MUST defeat all the trainers in a row to obtain a Perfect point!)
If You can get leadgandarys get it but put 1 Crap move in 2nd position they manly use that and make the level around 60
I Hope I helped ☻☻☻☻☻☻
A few more suggestions: Pokemon that know moves like Dragon Rage (like Gabite, Gible, Charmeleon, etc.) are great because they can do impressive damage against all types. Pokemon with high speed are handy, too (like Grovyle, Combusken) because, generally, no one's going to do that much damage, and whoever strikes first has the upper hand. And Pokemon that have moves that are super effective against a lot of Pokemon (like water, grass, and ground) are good choices, too. Good luck, I hate this colosseum!
try to use the Pokemon that are strong and that have super effective moves on his Pokemon
you Battle Pokemon the talk to the trainer
well you have to compete the waterfall Colosseum
The Colosseums are... The Gateway Colosseum, the Main Street Colosseum, the Waterfall Colosseum, the Neon Colosseum, the Crystal Colosseum, the Sunny Park Colosseum, the Magma Colosseum, the Sunset Colosseum, the Courtyard Colosseum, and the Stargazer Colosseum.
You can only unlock it by transfering a deoxys from a Pokemon DS or DSI game.
Well,if you mean a double battle its pretty easy. 1)Go to a colosseum. 2)Before you battle,go to the options and and click on double battle! 3)Then..........................The battle is ON!!!!!!!!!!!!!! IMPORTANT!!! (You have to choose a colosseum that lets you play double battles.)
you Battle Pokemon the talk to the trainer
For most of the colosseums, you have to beat 6 trainers, and then the 7th trainer you face will normally be that colosseum's leader
Only those from your Pokemon DS games are yours. Pokemon Battle Revolution is a blow-off because, unlike Pokemon Colosseum, there's no Pokemon you can "get".
You must defeat the Colosseum leader's, there are a total of 10 Colosseum in the game.
well you have to compete the waterfall Colosseum
The Colosseums are... The Gateway Colosseum, the Main Street Colosseum, the Waterfall Colosseum, the Neon Colosseum, the Crystal Colosseum, the Sunny Park Colosseum, the Magma Colosseum, the Sunset Colosseum, the Courtyard Colosseum, and the Stargazer Colosseum.
Courtyard, then the last Stargazer.
you need to battle a trainer with shadow Pokemon, you will be able to "snag" it. it will only have one move and will not be able to level up until you have purified it. it will then learn moves. this is the only way to catch Pokemon in Pokemon colosseum.
You can only unlock it by transfering a deoxys from a Pokemon DS or DSI game.
By defeating the leaders of each colosseum. You'll unlock new battle passes as you progress.
The Gateway Colosseum, the Main Street Colosseum, the Waterfall Colosseum, the Neon Colosseum, the Crystal Colosseum, the Sunny Park Colosseum, the Magma Colosseum, the Sunset Colosseum, the Courtyard Colosseum, and the Stargazer Colosseum. hope this helps!
you face six people then the seventh battle is the leader
