Parting Shot

As an additional cost to cast Parting Shot,
sacrifice a Vivien planeswalker.
Look at the top seven cards of your library. You
may put a creature card from among them onto
the battlefield. Put the rest on the bottom of your library in a random order. When a creature is put
onto the battlefield this way, it deals damage
equal to its power to target creature or
planeswalker an opponent controls.
