Nice decklist. Used it a few days to climb from rank 8 to 4. Started with your exact list, then later on added sandbinder and siamat as you already suggested and took out puzzlebox and tortollan pilgrim. So far I like the changes.

Only thing is that this deck still just gets overrun by aggro if they draw decent and we draw poorly. Not sure what the best anti-aggro cards is to put in and whether it's worth it. Tried Flame Ward for a while and it wasn't bad, but murlocs can play around it with Coldlight Seer and it's average against reborn creatures too. Maybe Bone Wraith as that's the most vulnerable turn against aggro with this deck imo. Or Rabble Bouncer. 

Kept running into (and losing to) huge mech creatures (venomizer/missile launcher or mechano-egg + taunt mech), so: 

+2 Ironbeak Owl

-1 Forest Aid

-1 Swipe 

(and I already swapped 2nd forest aid for ziliax).

Not sure if they're the right cuts, but the silence has won me a lot of games since)

Great deck, very effective against hunter indeed. Rank 8 --> 3 with just a few losses. So far your tech-choices are spot-on in my experience (1x medic, 1x holy fire, 1x roaster, elemental instead of acolyte).
