Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Just a small detail. You can optimize a bit that EVspread by using timid nature and 252 HP / 160 Def / 96 Spe. It gives you 1 more point in both Def and Spe.
I've search through the internet to check that I was right, and everywhere, people explains that it doesn't proect your allies if Aromatisse is not in the battle. That's very easy to make sure in a battle, although.
I see, np with that, there's still some time to play. Could you play at 22:00 or 23:00 (8:00-9:00 in GMT+11) or 10:00-11:00 (20:00-21:00 GMT+11)? They'd be the best for me.
