If you can get a breather turn to drop this on 3 or 4 vs aggro you can play ahead to soften a big board for Rolling Fireball or Reno.

Not a bad card, basically your deny a turn for your enemy (which vs aggro is a lifesaver)

It should say “Dormant for 2 turns. When this awakens, you gonna be already dead, so who cares”

This card is nuts. It will totally be a meta card and we will se this a lot. As someone already said, one of its biggest strengths comes from the fact that your opponent will have to play around this for two turns ahead, which in the case of an aggro player would be almost devastating. It is a very solid card. 

it look to be in wrong class this card look like it should be Druid,Warlock or new demon hunter for 4 reasons

1.like first off it a demon so not for mage (mage mostly Dragon/Elementals or blank) 

2.then got sacrifice 2 turns after play it to even use it to do damage (mage is no downside class so that clue 2 it in wrong class)

3.it a minion AOE and not a Spell AOE so why would this be here?

4.let be realistic it bit of a control card and why would they give the heavy magic class more control chooses

over all this must be a mistake on blizzard end 

Isn’t this the same image as “chaos gazer”...  just changed a little?  Is that intentional?

As a defensive tool, its pretty garbage. For the same mana cost, you have flame ward who pretty much pushes the damage immediately. 

As an offensive tool, this card is terribly slow

Not entirely. The strength of this comes from the fact that your enemy has to alter the way they play for a few turns. And its not like Mage will count on this as their only option for defense. You can build your board as you like because this only hurts enemies. Though it could be a bit stronger.

Coining this on turn 2 is bonkers if Aggro Mage becomes a thing.
