CURATOR COMMENT-Who is the artist that made the picture? If there's no source for the art piece, it cannot be moved up.
I'm okay with the idea, but to pull this off alongside a Ghost+Nightmare combo seems a bit complicated and dreary to do. The 'Recall' function/card is a nice balancing factor, although it still cripples rainbow decks that rely on unprotected Eternities or other cards that have abilities that need to be used immediately.
The best thing about this is that you can basically 'refresh' one of your permanents as necessary, like Phase Shield or Sundial...
