I just came up against this and got destroyed. Ridiculously powerful vs anything that uses minions to win. 

if they run double spells then you can't exactly win too often and most likely be destroyed.

You can Naturalize your own Coldlights, still forcing your opponent to draw 2. This consistently beats Ice Block + Fireball and Ice Block + Forgotten Torch, for example. I win far more than I lose with this.

It doesn't stand a chance against decks with lots of 1-mana threats, though. So Mages running lots of Arcane Missiles or Ice Lance; priests with Mind Blast; or those murloc decks with any combination of Grimscale Oracle, Murloc Tidecaller, Bilefin Tidehunter, and Murloc Tidehunter. They're able to burn you down before fatigue kicks in or fill the board faster than you can clear it.

There are also a few Druid decks, like Innervate + Deathwing, Dragonlord, that counter this perfectly.

your'e absolutely right. Do you mind if I put that in the description of this deck and credit you?

Absolutely :)
