I am showing these more for my own future use than to share them. I didn't even know I had two Serum Visions! Promos are handed out for spending money on Magic Online and I sometimes don't look to see what promos are being awarded. This way I know about the ones I currently have. The play set of Path to Exile are a bonus because after players got the wrong one, Wizards, awarded (I guess everyone?) a free play set. That is so awesome. Maybe someday I can give these to a friend.
The only promos I have purchased are these Wurmcoil Engines.
