A lot of luck. The only way Mirage Island will show up in your game is if the randomly generated ID # for Mirage Island matches with the ID # of the first Pokemon in your party. So in order to even have a CHANCE at seeing mirage Island, you'll need to catch LOTS of Pokemon. And I mean finishing the whole Pokedex and catching duplicates as well. If you see it sooner though, consider yourself extremely lucky.
You can't...without cheating.
never heard of little island. what's on it?
the way to get to birth island is to get the auroua ticket
in navel island with Nintendo event or cheating
You can't catch Deoxys without having gone to a Nintendo Event (which has been passed for several years now) where you get something that allows you to go to the island where you can catch Deoxys, or without cheating. It's impossible.
get the ticket to birth island and solve the puzzle. You can only get the ticket from a Nintendo event or cheating.
