Brawl really good at turning the game around lol

possible to post the list here? or some imgur (office cant open hearthpwn)

I not understand about it, suppose they say let us pay 700 gold to unlock 1 wing, there are 5 wing and 1 wing is free, why I can't find other 4 wing to unlock by gold?
Yesterday I try and finish the easier level, then the second one is let us use their druid and rogue deck to beat, that one also win already. Now only left the hardest. That one, the first part spider can win easily. The second one which use 1 mana and deal dmg base on how many card you have in hand (really need to adjust my deck for it), third is use 0 mana and put back your 2 creep into hand (these really need to use low mana and rush deck with battlecry). You all finish those already?
