>>27421229I don't feel like it, I mean Arceus would be an event so if they ever gave us the Azure Flute the information would be right on the Wonder Card, or on their websites event information, or if it was a GameStop/EB games promo it would be on the cards you get your individual codes on.
As for recatchable: most likely. It could go either way. We did get a level 1 Regigias in Platinum right after the one we got one in Diamond and Pearl. Since Regigias probably won't be in Sun and Moon, and Sun and Moon are generation seven, people who are starting over without access to Bank could get another one this way. They made Regigigas catchable in Black and White 2 as well.
