Now if the UG lands player doesn't have a sufficient landfall threat on the board, he or she can still find value in returning their lands to hand, discarding them for value (maybe to Wild Mongrel, Noose Constrictor, etc., or Turntimber Sower, if not Trade Routes), and having options to re-play them for future landfall triggers or other shenanigans
Be sure that this card has a first edition stamp on the center left corner
