No, you don't get Deoxys on Mirage Island, and Team Rocket isn't on it either. You can catch Wobbuffets though... really high level ones. Plus, the Leichi berry plant is on Mirage Island.
Getting on mirage island is tricky... but it can be done. Here's how I did it:
The appearance of Mirage island depends on the IVs of the Pokemon in your party (I think), so what I did was trade out for new party Pokemon with the Pokemon in my PC and revisit the hut where that man is looking for Mirage island. If one of your Pokemon is an IV match, instead of mumbling something about not seeing Mirage island, he'll say "????". That's how you know it's out there.
A word of caution, though. In order to get to Mirage Island from that hut, you need to have a Pokemon who knows surf. Make sure that each set of six that you take to the hut has at least one pokemon who knows surf. Another good thing to keep in mind is all the high-level Wobbuffets on Mirage Island. I'd make sure you also have a Pokemon with you that can defeat a level 45+ Wobbuffet pretty easily - because with Wobbuffet's ability, you won't be able to flee any of the battles.
You don't necessarily have to know what IV is called for, nor do you have to know what the IVs are for any of your pokemon. All you have to know is that the required number changes daily, and that's enough to get you started. Hope that helps!
