My Alien Roommate: Magic

Ok, I have a standard deck of cards, they are in a random order, like you saw me before. Now take one completely of your own free will. Now replace it in an arbitrary position. Okay, now I'll randomize the cards again and your card will be at the bottom. So what just happened? I told you a series of lies. Okay, what do I do now? I will try to find out exactly when and where I lied and what the result is. If I succeed, you will ruin the whole experience and if I fail you. You will spend the rest of your life in ignorance.
