So it's a +1 mana cost +2 damage fireball that can't target face ? I dunno i don't think it's that good. Will propably see play but mages already have great removal. Will propably add one in my deck and try it out.
Edit : It does insta kill a Ragnaros though which, if TGT is succesful, will see a lot of play once more being slower, more control-ish and all. But still BGH is the go to big minions removal.
I don't know if it will be used because of its lack of versatility but it might have a place as a tech card to beat Handlock. I do think it is a nice cheap control card if nothing else. This will take down every threat except half of the 9+ Dragons. For budget decks its probably a staple. I like it!
