  Official Ruling
  If the target creature is an illegal target by the time Judge Unworthy tries to resolve, the spell doesn't resolve. You don't scry 3 or reveal any card.

  Official Ruling
  Destroying a blocking creature won't cause any of the creatures it was blocking to become unblocked. They won't deal combat damage to the defending player or planeswalker (unless they have trample).
