That Avian Watcher probably only reasonable in mage and even secret paly, in hunter? eh, I'm not sure about that. You need to have secret for it to even have taunt unfortunately, you can't play it as a fen creeper. Hunter can't draw cards for these combo wombos be worth running. They probably have to give hunter a card that draws secrets for any of this to work reliably.
I can see some kind of control mage with iceblock, medivh's valet and that card work. When I started hearthstone I was playing control mage for a long time, I like to go back to it. It's the most fun control deck and these cards seem strong enough.
