On the event day use the mystery gift on the time of the event (you must be in a place that has wi-fi connection) and if you're lucky you should get the event item (examply Azure flute = Arceus). When you've got the item, continue the game. Go to any normal Poke-mart, and you will see a man in green next to the shopkeepers. Talk to him and he'll give you the item you have got through the mystery gift. After you get the item, you can unlock the place for the pokemon and capture it.
When you get the Azure flute, go to Mt. Coronet and to the Spear pillar and the place where you battled (and maybe caught?) Dialga or Palkia. When you enter the summit, a thing will appear ssaying, that the Azure flute is glowing and asks if you want to play it. Say "yes" and you will "play" a melody of the flute. After this a long "glowing" staircase will appear infront of you and when you go up, Arceus awates for you. Be prepaired as he's on lv. 80!
When you get the Oak's letter, go to route 224 and at the end, prof. Oak should be standing next to the light coloured big boulder. Talk to him and he'll ask you to move it with him. As you try, something will happen. A long flovery path will appear and the whole place turns into a big flovery place. Follow the path (I recommend using a bike, as the path is REALLY long) and at the end of the path, Shaymin awates. He's on lv. 30.
When you obtain this item, go to Canalave city and go to the motell, that has been closed before this event item. Go for a night sleep and you will be disturbed by Darkrai there. After you wake up a diary has appeared with the location of Darkrai. Now go to the sailor (who took you to Iron island and Fullmoon island) and now he will take you to New moon island where the 40 lv Darkrai is.
