re: brawl list
freeze mage feels really solid right now. This is a list I adapted from Thijs's freeze list he went 12 wins with:
So, basically he has -1 blizzard, +1 barrier, +1 arcanologist
I find arcanologist to be pretty unnecessary in the deck and often a dead card or makes my mad scientists dead cards more easily. It's fairly easy to get a block up, don't feel the need for the extra secret draw. I'd rather have novice engineer. 2 blizzards seems core for this deck, not sure why he was rocking just the one. I kind of get it - with medivhs valet, you're able to control the early game much easier and need less stall mechanics later on. Still am never ever sad with a blizzard in my hand so I went with 2. With all the control on ladder right now I don't feel the second barrier is necessary, I already feel heavily favored vs PW and aggro shaman. This deck sacrifices a little draw for the power and flexibility of primordial glyph, which has incredible synergy with antonidas. Antonidas gives you reach and a little surprise factor. I'd be willing to mess around with malygos in this list as well.
The other package I would run is the heavy OTK deck with the zeus package, but honestly, I find it unreliable.
