The only way for you to get Deoxys in "Pokémon Colosseum" is to download the Aurora Ticket via a Nintendo distribution event or to use a cheating device such as a GameShark in order to get an Aurora Ticket in Pokémon FireRed, Pokémon LeafGreen or Pokémon Emerald and then you can use it to travel to Birth Island which is where you can catch Deoxys at. After catching it, you can trade it into "Colosseum," this is the only way to get Deoxys into "Colosseum" other than cheating it into the game.
