Cardaclysm

You are a dark wizard who shouldn't have tinkered with magic and spells way too powerful for you. But you did. And this time you messed up really bad: You've unleashed The Four Horsemen of the Apocalypse and their minions upon the World! Well done...

So hurry, grab your magical cards and send them all back to their hellish dimension before the Apocalypse destroys everyone and everything - and much more importantly, before the old wizard council discovers what you have done...
