Calamity

For each player, destroy one target nonland permanent that player controls. Then, each player discards a card and loses 2 life.
Despite what you believe. I am not your enemy. Unless you wish me to be. I am not Tartarus or some fanatic. I am not Truth. I am not Regret. I am their remedy. As such I can spare your lives. Or, just as easily end them. - Atriox
