Question

if you do a wi-fi event can you do it again?

Answer 1

>Players are able to receive gifts wirelessly, from the Nintendo Wi-Fi Connection or from a friend. The Mystery Gift feature will only allow a specific gift to be received once. As a result, a player can only get one of each item and Pokémon from the said games and also only one of Pokémon from the Events.

Nope, you can't.
I've tried, like a million times.
Sorry
