Rising Populace

• WWizards of the Coast2019-05-03
  Official Ruling
  If Rising Populace and another creature you control die simultaneously (perhaps because they were both dealt lethal damage in combat), Rising Populace won’t be on the battlefield as its triggered ability resolves. It can’t be saved by the +1/+1 counter that would have been put on it.

  Official Ruling
  If a planeswalker that’s also a creature dies, Rising Populace’s ability triggers only once.
