Hearthpwn

Elite card 

Put a new golden version, pls. This has a brighteness lag

I m gonna try this card for sure !!!

This could be really good with The Soularium. Draw 3, turn them into demons, and get +6/+6 in stats for 3 mana is really good in a zoo deck that just wants to throw stats onto the battlefield. 

Soularium going wild :/

So? Good in wild, then.

This is wicked

IDk this card might single handedly allow you to run a deck of almost exclusively control tools and just win in the late game with the giant threats this adds to your hand.

Even a card like Flame Imp becomes a threat with the buff. This seems really good in control style Warlock decks. We just need to see how those pan out. 

A nice option to have if your hand's full of removal or trash. Just having it in the discovery pool for Ethereal Lackey and Twisted Knowledge is a plus.

Probably 3. Play a 1 drop on turn one, tap twice and then drop this, you hit 7 cards, 8 if you have the coin.

This kind of card allow you to use a deck with many tech cards because you can trade the useless ones for random buffed demons.
