Edit2: Thinking about it, it would be maybe too strong for some classes. Changed the rarity and made it so it's a Hunter card. Could be a great asset for more control-oriented Hunter decks (also, there's not Hunter 8-drop at the moment).
Although there have been Mill Decks almost since release, we have never had a card specifically designed to that type of decks. It fills the gap of a big threat mid game, which will help you get to fatigue late game, where your win condition is.
Flavor Text: "A long-long time ago Malfurion was trapped in the Emerald Nightmare. Seems like he didn't go on with some of the trees."
Trivia: Based off the Emelard Nightmare (WoW wiki link: http://wowwiki.wikia.com/wiki/Emerald_Nightmare), it pretty much stands up for itself. Simular to demons, it has a GIGANTIC body and a very punishing effect. Again, nothing to say there. Giants must be simple.
When put onto the battlefield: "Ghueeeeerckhhh..."
Edit: I recieved some messages about this just being a Better Mogor's Champion. I didn't think about that card when i ran the numbers with this but i think this statline is perfectly fine for a 6 mana Ogre It's just Ogre Brute X2 in power and cost. See it as a power creep to Mogor's Champion Just Like Evil Heckler is to Booty Bay Bodyguard, It's not like they are gonna make it anyways...
