I can't wait for this, I love Blackrock Mountain in Warcraft! :D
Freeze fatigue mage?
I think mage would work. Particularly with secrets like vaporize and mirror entity. Shove mostly big minions in your deck and rely on removal spells for the rest. Ragnaros and Sylvanos would be good and you need to avoid battlecry minions. Counterspell might hopefully stop his Brawl spells...
Priest could also work. Thinks like Shadow Madness could take his minions and use them against him (depending on how big his minions are).
And so, the F2P people get even more screwed over. Its fair enough to make expansions cost money, for obvious reasons, but they should at least make it plausible for normal players to afford them without grinding daily for several weeks. Hopefully it won't be the same situation as Naxxramas where one of, if not the best, legendary in the game (Loatheb) is effectively gated off from those who do not have the time to grind for nor the money to get the expansion.
People who want everything for free should be screwed over, in my opinion. Why should Blizzard do all that work and not get paid for it?The fact that there's the possibility of getting added content for free at all is excessively generous in my opinion. There aren't that many computer games out there that don't cost a penny for their expansions.
