Hearthpwn

Quest druid hasn't lost a lot of power besides Floop and Loti, which were pretty strong. But now we've got a lot of new tools as well. 

We've got some early game defensive mechanisms in cards likeMaiev Shadowsong and Archspore Msshi'fn and we even added value generators like Marsh Hydra. I've checked the 8 mana pool and almost half of the minions are minions Quest Druid probably would run if they had the opportunity to do so. 

Ysiel Windsinger isn't a necessary card if you lack dust but can create insane swing turns with stuff like Nourish that draws you 3 cards and get you 2 extra mana crystals to play more 1-cost spells.

Earlier we've also had the problem of leaving our face free to be attacked when we play Ysera, Unleashed, but with the new Ironbark you can play Ysera and get a 5/15 taunt minion.
