The thing is: The attempt of this game isn't pure balance. It's based on the Witcher series. E.g. Yennefer will always be able to beat Triss, it's a fact. If you just want to count numbers, play something else. This game is about knowing popular decks and how to deal with it. In other words, being aware of your opponents potential. Defenders are easy to defeat. All you need is a purify and some damage. A general advice: Don't try to play against cards. Try to play around them.
