A random card will be picked from your deck. In order to play it, you need to pay the card's mana cost, plus other factors like having a target to cast a buff on, space on the board for another minion, not already having a copy of that secret already in play, and so on. If you fail to meet all these conditions, the card is removed from your deck without having any effect. Either way, the process repeats a second time.
