if you see to many of that kinda deck, play an aggro deck, even with the freeze,flamestrike, blizzard, if all your guys have charge it wont matter. Follow up with big beefies where they have to waste their spells to kill them, instead of you.
There are WAY tons of counters to this, just think outside the box on creation..
Besides all else, ITS BETA!! THIS ISNT FINAL GAME
The only thing I dont like is the MC nerf, I see why its needed, but its either MC, or heal, and sometimes that makes me lose. Yes 10 turns lets people have their big guy out, but we miss a heal because we have to use all our mana to MC, and its not worth it unless we were winning anyways most of the time. Lost a game earlier cause I either had to MC or heal, if mc was still 8 mana, I would have lived but with the 10, not only does it take all my mana, I have to wait 10 turns to use it. I think the nerf should have been (costs 10 mana, but your next spell/ability this turn costs 2 less) that way still had to wait till turn 10, but you dont lose the 2 mana you would have used on something else
