Probably true, but it would take a hell of a long time (or so i’d imagine) to create an entire deck potentially stuffed with hundreds, or even a thousand words.

I’ve had a routine back when I was more actively doing language learning: set aside one day of the week to create cards, just a couple to a handful or so (which for cloze cards with an average of five items, would already be a good number). Little by little that deck would grow.

In particular, I’ve had a French grammar and a Japanese vocabulary deck I grew that way. The Japanese deck contained vocabulary words from the textbooks I used (mostly Genki I and II) and at the moment has 1.97k cards The French grammar deck had snippets from a grammar reference book and at the moment has 603 cards. Not much, but I tend not to add more cards until I really need to (pending reviews down to almost zero).

I’ve long resigned to the fact that doing Anki is a very long game, and there’s no use creating hundreds of cards in a weekend if I can get away with creating a handful every now and then.
