Flashcards to learn Blackjack strategy table?
Yes, there are flash cards in the excellent book by Ken Uston titled "Million Dollar Blackjack"  This is a great book with interesting stories and strategies for different house rules.  Applies to counters and non-counters; single, double, and multiple deck games.  Vegas, Reno, AC rules explained as well.  I think you can find it for less than $20.
