You are not able to play it because of Hidden Lurker's Text.
Usable only by an untapped vampire other than the acting minion after the
acting minion is ***blocked and combat is over***. Tap this vampire. This
vampire now enters combat with the blocking minion. The firs round of
combat, the blocking minion cannot use any strikes.
Change of Target cancels the action and the ensuing combat, so therefore,
you may not play Hidden lurker or Fast Reactions or Coordinate Attack.
