alt Hacker NewsFrequency lists are very useful but learners need context in order to use them, because little word atoms like prepositions, pronouns etc are heavily over represented in the core set. So make sure to study how to use those, and master the core to be/to have verbs too. Some languages have two verbs that roughly translate as to be so you need to crack that too.
Beware free lists on Ankiweb. They are very variable in quality. Frankly better to build your own.
I am constructing my own. Examples are drawn from books, group chats, podcasts, and other media that I consume in the target language (so I know those are either correct, or at worst, as wrong as native speakers are which is good enough for me), shortened as necessary to make it appropriate for Anki
Then I gave my first 100 cards to a native speaker and somehow it's still full of subtle issues and not infrequently also actual mistakes >.<
The two dozen decks I've downloaded aren't always perfect either, but making your own doesn't guarantee it'll be better than another uploader's honest attempt at making a good deck. I do wish Ankiweb was more collaborative though, at least having a bugtracker where people can report mistakes and additions, if not full on code forge functionality. If I'm not mistaken, all you can currently do is leave a review
