Hi! I had to delete your page because pages are not meant for questions and answers, if you have any question at all you can open a discussion in the forum.

But to answer your question: once you use a card it can't be undone, so if you used the wrong card by accident you lost it forever. Be sure to lock as favorites the cards you don't want to lose, so that they'll always be greyed out.
