Use the recycling cards which will bring back the Moves, Corners or other cards which will be of the most help to you. This strategy effectively increases both the size and power of your deck and helps ensure that your key cards aren't lost in Damage resolution. If you have multiple Second Wind cards in your deck, it's usually a good idea to hold one of them in your hand until you see one or more of the others in your discard pile. Then, you can play the one from your hand to get back the others which would otherwise have been lost. To counter an opponent's ability to recycle cards, consider adding Doug Dillinger to your deck.
