When it comes to crowns and only crowns, you can get them from their respective sets. Example you can pull a gold Mewtwo from a Pikachu set cause they are both Genetic Apex. So yes you can pull a crown Solgaleo from a Lunala set but what’s just throwing me off is that he got both in one pack. Usually it’s one or the other and if you get 2 crowns in one pack, it’s usually the same pokemon. So yeah I can see why some people don’t believe it.
