Apostle of Invasion

  Official Ruling
  In a multiplayer game, Apostle of Invasion can lose double strike after dealing damage in the first combat damage step if all the opponents that had three or more poison counters left the game. (This is most likely due to that combat damage, so good job!). In that case, it will not deal any combat damage in the regular combat damage step.
