Need help with Rock Duel Highlander DH

I want to create a Highlander DH deck with Elite Tauren Champion, but I'm really really bad in deckbuilding, so I ask you to help me improve it.

Why I think that it's a fun idea? First of all, Reno, Lone Ranger works well with Molten Pick of ROCK: with only one board slot opponent is limited with what they can play, so it's more likely to detonate the Pick.

Demon Hunter has other tools to make it awkward for opponent: Prosecutor Mel'tranix limits them to leftmost and rightmost cards, Gunslinger Kurtrus has a chance to eat a minion or two, which also limits their options.

Additionally, DH has plenty of cheap cards and ways to refill the hand. This and 1-cost HP make it easier to use all your mana and avoid blowing the Pick on your turn.

This is my deck. I will appreciate any suggestions.

If you want to make an ETC demon hunter there are a few cards you could consider.

First of all, to decrease the likelihood of the pick exploding on your turn you might want to include card generation like Snake Eyes and Ghost Writer to discover cards to fill the curve.

On the more gimmicky side you could run Storm Giant to ensure you spend all of your remaining mana by dumping it in extra forges, in the case your remaining mana is odd you would just have to use your hero power (provided you're not Reno yet)

The other cards you suggested (Prosecutor Mel'tranix, Reno, Lone Ranger) work pretty well for making the opponent explode once the pick gains enough damage.

Overall the idea of the deck is cool but keep in mind that in the case the opponent decides to tank the 8 damages early on there's not much you can do to avoid it, so you would at least have to run an alternative win condition.

Thanks everyone for suggestions.

I've been playing this deck for a few days and my problem is opponents usually manage to use all they mana for long enough to kill me. This deck struggles with late game board pressure, so it needs either more removals or some board pressure of its own.

I very much like this idea. I took your deck as a starting point, removed the weaker cards, and replaced them with cards from a deck I was playing previously. I will definitely try this out.
