I defeated that deck once as control warrior, but I've removed the deck unfortunately. My suggestion would improve your early game a bit and sacrifice value cards such as Archivist and add some cards to remove early game threat like execute (Yes I actually add two of them and one Devastate, despite that's the reason why I won the game in controlling early game). But in that tournament mode, that seems a bit risky since you need to win against other matchups.

And I'm not really sure about going against mech hunter, I went mech hunter just to direct counter warrior. There is still a chance if you can build around the deck against Mech Hunter, execute seems to be much better than EMP Operative. Also, it will be hard to pull that off as I almost lost the game against Mech Hunter. Going against mech hunter, you're going to need a bit of tech and lots of luck if you want to win against your big enemy.
