I recently found out that AnkiHub does not support moving cards to different decks. As a deck maintainer, we have made lots of organizational changes such as moving cards to different decks & deleting decks altogether due to redundancy.
I’m surprised this feature does not already exist, since it is such a basic feature, & is integral to using Anki. Being able to reorganize decks can improve the quality of those decks as it makes it easier to find & study specific topics.
