"National Pokedex - Event Only Pokemon"

With Pokemon Home Arceus and BDSP integration I’ve finally deposited my remaining Pokemon and my Pokedex now shows 900.As far as I can tell Victini, Meloetta, Diancie, Hoopa and Zeraora were all event Pokemon so there’s no way I can catch these now? I can only hope they get reintroduced in a future game / remake? Or GTS I guess but I’d rather catch them myself and due to the scarcity would they just be hacked event pokemon on there?Is there any way to complete the national dex now? via /r/pokemon https://ift.tt/ZBp32lF
