Hunter Mecha'thun

Hello guys, so, I'm a big fan of Mecha'thun decks and so I created this deck. I want to know if you guys can help me improving it because I'm sure it has a great potential.

The combo is easy : Use Galvanizer twice on Mecha'thun then play it on turn 10 with Goblin Prank. The only thing is that you have to empty your hand first with this combo and I had trouble with that.

- like every Mecha'thun deck there's a lot of draw (maybe too much in mine), we have Acolyte of Pain, Novice Engineer, Loot Hoarder for the draw, Ursatron who can bring any 3 out of 4 combo pieces or zilliax and Tracking to draw a card and take off 2 others (I highly recomend to use it once you have at least 3 pieces out of 4 of the combo, just in case) a

- Shimmerfly, Animal Companion, Explosive Trap, Belligerent Gnome, Zilliax, Rotten Applebaum, Lifedrinker are all cards for the sustain and to stay alive through the game.

-Nine Lives can be really helpfull. Against aggro deck, you can try to catch a rotten applebaum and against control you just have to get more draw minions.

-Flare : What to say with choice, I think it's ok because of all the paladin secrets, there's some hunter/mage playing annoying secrets and even if you don't play against secrets it's still a draw but I'm not sure about it

Some combos I like: Using rapid fire against my own acolyte of pain can be usefull or with thalnos for 2 mana 4dmg.
