What was the last valuable card you misplaced? I'll go first...

Just got the Eldrazi Unleashed deck and went to start modifying it. Lo and behold, my [[Void Winnower]] seems to have been lost to the Blind Eternities. Every deck and storage box has been searched. It's just gone.

So, how about you? Did a [[Stoneforge Mystic]] fall between the cushions of your couch? Maybe a [[Dockside Extortionist]] decided to go for a walk around the pier? A [[Deflecting Swat]] that vanished on some stack?
