Why is Necrozma being advertised right at the beginning of the gen?
Giratina, Kyurem and Zygarde only started being relevant a few years into their respective gens. Before that they barely got mentioned in official sites and didn't appear in any kind of merch. But Necrozma not only was one of the last "secrets" revealed before SM's release, but it's getting into the TCG not even a year since gen 7 started.
Is this generation going to be super short or what?
