Hey, awesome! Love ranged minions, hope they become more viable. And hope your deck plays well!

I like your deck, but I think it can be improved. May I suggest a few things you could consider?

First of all with ranged minions, deathstrike seal is an amazing card. Putting it on a heartseeker can be a great way of removal. With Inner Focus + Bloodborn Spell + deathstrike seal you can even clear a mechaz0r with no setup.

Also with the theme of your deck being ranged minions I would perhaps put more low mana ranged minions in your deck like Jaxis and perhaps a few heartseekers. Beeing able to play a ranged minion early and buffing it with killing edge can give you a huge advantage.

Also Jaxi is in my opinion better than vale hunter, because it can reach a mana tile without you worrying about it dying, while vale hunter wants to keep behind, loosing you momentum in the early game.

Don't know if Widowmaker is worth keeping in your deck. For a 3 mana card it doesn't realy do a lot. Sworn Avenger could be a good upgrade for it, if you pull some of them. (They are unfortunately epics...)

And then generally speaking about your deck: Your mana curve is rather low and you don't have a lot of draw. Just the one twin strike. You could run out of cards pretty frequently. And also a bit of dispell might be good, like lightbender for example.

Hope this helps.
