Impending Flux (Extended Art) [Doctor Who]

Paradox — Impending Flux deals X damage to each opponent and each creature they control, where X is 1 plus the number of spells you've cast from anywhere other than your hand this turn.
Foretell {1}{R}{R} (During your turn, you may pay 2 and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
