This is fine in a custom cardset, but there are... some complications that makes me suspect Wizards wouldn't print this. I'm actually not sure if Vulturous Zombie or Emrakul, the Aeons Torn would trigger with this out or not, due to the "from anywhere".

Since "dies" refers explicitly to a creature's moving from the battlefield to the graveyard, the two cards you've mentioned would not trigger in that specific case but would still trigger if a player was milled. I don't think this is any more confusing than Anafenza, the Foremost's interaction with a bestow creature that would move to a graveyard while it was aura, or an unanimated god that somehow died.

No, there's more to it than that. Based on the Yixlid Jailer rulings, I suspect the two I mentioned would trigger. But most players wouldn't know that for sure!

­Yixlid Jailer's ruling specifically point out that it still allows "dying" to trigger, since it triggers from the battlefield. Saying "from anywhere" in the text of the card doesn't modify what is actually taking place. The zones the card moves between are still the same zones. If Emrakul moves from the battlefield to the graveyard, it has still "died," even though its ability doesn't call that out
