OK, so I got both games, but am using gold as my main. Now, i just got the 16th badge, and am now gonna do a bunch of side quests and events. I'm about to do the Arceus event next, but i have a question/idea. I'm thinking of doing the event and getting one of the poke-gods, then trading Arceus to a new silver game, getting the second poke-god, trade both it and Arceus back to gold, resetting the silver game, trading Arceus over again, getting the third poke-god, and then trading them back to gold again so i'll have all three.
Now my question is: When is the earliest i can activate the event? Can i do it as soon as i first reach the ruins of alph, or do i have to wait 'till later? Hopefully i can just do it right away, since i'd only have to get through to the first gym and wouldn't really be losing much progress when i'd reset after that.
