Good call on #1, I will get that fixed. #2 means destroying all face cards in the deck, Jacks, Queens and Kings. They can be destroyed with Bombs (non standard card), the Snurf Blaster bauble, and the Cake bauble.
Edit - to clarify, specifically there is a check after each hand played that counts the number of face cards in your deck, and if it is 0, unlocks that deck. So if you've added more face cards to your deck, all of them need be destroyed.
