Valor, Existential Goddess

{w/b}{w/b}{w/b}{w/b} - The world around Valor loses stability, and terrain temporarily blinks out
of existence. For the next two of the
summoner's turns, all existing land cards are removed from play. Any newly played land cards act like normal.
At the end of the second turn the summoner
of this card, all "deleted" land cards return
and act as if tapped until Upkeep.
