Should booster cards be marked as new?
In some unlocking mechanisms of booster cards, there is the option to either tell the learner that the card is a booster card or to leave it visually indistinguishable from existing cards in the deck. It's not clear to me which is better. Casually mixing in new cards without telling the learner could be jarring, but it could also help them pay more attention and to not just state their pattern-matched response.
