As others pointed out Steam Surger is a dead and very expensive card, you could play a 3 cards instead of playing one for 4 mana.
Also my humble opinion: Blizzard and Frost Nova should be swapped, 2 Frost Nova and 1 Blizzard, you don't care about clearing the board much but stalling it and 6 mana is too much, Frost Nova also it's easier to combo with Doomsayer.
If it works for you it's fine of course.
This is my variant
- 1x Blizzard | +1x Frost Nova
- 1x Acolyte of Pain | +1x Novice Engineer
- 2x Steam Surger | + 2x Dirty Rat or + 1x Dirty Rat + 1x Cabalist's Tome
Dirty Rat work wonders against all Quests and especially Rogue ones.
Cabalist's Tome is indeed clunky and might clog your hand but i found it very useful a lot of times so i put it back.

I suggest -2 Steam Surger and +1 Cabalist's Tome and +1 Card Draw card to cycle through the deck faster

Drakonid Operative is one of the reasons why you play dragon priest

The funniest part is that you might not have tried the deck at all, and is mocking it for having 1 taunt and 1 heal when it has alot more than that
