Grim Flayer One of my personal favorites of the set, Grim Flayer is currently held back by matching up poorly against Sylvan Advocate
They are also popular with collectors
If you get it right, theres money to be made, with even outsiders to the game picking up Reserved Lists cards as part of their portfolio
