You need a full inventory of Pokemon to get to Mirage island. You Pokemon give a random number and if it matches with the old man who watches the island, then you can go to Mirage island. Mirage island will only be available for that day.
You do not need any items. All you need is a very hard luck. The ID number of the first Pokémon in your party should match with the floating point number of the mirage island. If it matches, talk to the man in Pacifidlog. You can now travel to mirage island.
