Magicon random card

Got home from magiogon Sunday was showing my wife some of the stuff I got. When she pointed out the card in the side mesh pocket of my bag. I was like what do you mean? Because as a sane mtg play i wouldn't put a card somewhere that would get damaged. Come to find out this was in there and I have never bought a DMU pack in my life lmao. Has this happened to anyone else?
