I think that just about covers it! And also, there's something called a Card Roulette every other weekend (this weekend is the next one). On the first day, you enter up to five cards you don't want AND request another card (that you don't have but want) to be entered as well. The second day, they shuffle all the cards and hand them out randomly, including the three requested cards that the Cards Team has randomly picked. You'll get the same number of cards as the number of unwanted cards you entered, and there's a tiny chance you'll get back one of the original ones, but in my experience, it's only happened to me once or twice.
