  Official Ruling
  If this creature deals combat damage to multiple players simultaneously, perhaps because some combat damage was redirected, its ability will trigger for each of those players.

  Official Ruling
  The +1/+1 counter isn’t put on the creature in time to increase the amount of combat damage dealt during that combat step.
