I crafted Yogg, he just killed me.
Had a game against a priest that played a 19+ C'thun twice and I won. First time he played it he activated Ice Block, I had another one in my hand so played that. His C'thun died on my Vaporize. He rezzed it with that minion card. Played it again and activated my Ice Block again.
I played Yogg, who kill his C'thun and put among other thing an Ice Block on me...I eventually won.
It was hilarious. Yogg doesn't seem to be that good, but it's hilarious. He kinda fit easily in a mage deck that cast lots of spells anyways.
Damn the meta is unpredictable right now., but fun.
