"I'll SPLIT YOUR SOUL APART!" - some demon minion

i don't think this is from [Ashes of Outland]

What Gdw said.  According to the official Hearthstone card library, this card belongs to the "Demon Hunter Initiate" set.

For now the demons of Demon Hunter are weak, the only good candidates that I see are: that demon that summon a demon from your deck and the sleeping demon 10/6. But anyway they are already for the lategame and even so it does not work for you. It is also worse than Molten Reflection.

You don't know for sure. In my opinion, demons from demon hunter will be pretty strong from midgame to lategame and so on, plus, all the cards haven't been revealed yet. This card will not be weak, that's for sure.
