My 'immune' card is jack. It loses power and gets destroyed. Immune means it shouldn't. The hell. Not to mention that, but the enemy ALWAYS seems to get the cards it wants, and it sees where I put them. It's just because of a random number generator that I won some of those duels, which is ridiculous because they get to set their decks up from the onset. My deck can have super-crazy ramp-up of their power.
Not to mention every five seconds it's peddling something that I have to literally pay for. If I wanted that I'd go to Farmville. I'm done with this game.
