He agrees to the sale. The next customer agrees as well, this one to a nine-point-five-condition Antiquities Mishra's Workshop, which adds a whopping three colorless mana to your pool.

"$350?" she says. "This is bullshit. You can't get an Unlimited Edition Ancestral Recall for under a grand, anywhere. What's wrong with it?"
I look nervous, and then, just as she starts to turn away, I sheepishly offer a confession: "Okay fine. I grabbed a backpack out of a car last week. And I just want to unload them quick, okay?"
Nothing says "Honesty" like the word of a petty burglar.
"Ahhh," she says. "Okay." For a player desperate enough, fenced goods are an acceptable resort to stoop to. She buys the card. But I make my way to the exit, just in case her next visit is to security.
The truth is, I didn't steal the card out of anyone's car. I printed it myself, and back in my apartment are 500 identical fakes just like it. I'll let you decide which crime is worse.
