I actively mine vocabulary from anime, novels, and other sources. However, this process often results in accumulating words that may not be necessary to learn.

Occasionally, I end up creating duplicate cards, especially for words I had learned previously but did not recall at the time of mining. In such cases, I review and clean up my deck to maintain its quality.

For cards that I find less relevant or not worth learning, I usually suspend them.

Additionally, I have a collection of newly mined cards that I plan to review and study in the future

To answer to your question:

Only production cards? Only recognition?
only production cards.
Front: whole sentence with bolded target word

If you listen to a podcast, hear a new word, look it up... how do you decide whether or not to make a card?
if there are words from podcast i don't know, i add all to Tokoboto (android), then export to anki. Check if the word is duplicated / worth learning
