Why these decks?
Honestly, there are plenty of good free decks out there. If one already works for you, keep using it. These are for people who learn from the videos: every card matches a lesson line for line, with the same art, the same order and the same words. Watch it, then lock it in. All decks are free for now, so try them and see if they help.
Why flashcards at all? Spacing out your review and testing yourself are two of the best-supported study methods in learning research. Anki does both for you automatically.
