Jundslinging Peasants

I am currently trying to do the impossible. I seek to build a deck that could possibly get me to Masters that is strictly peasant (all commons and uncommons).

The Deck
- I want to like this gunslinger deck so bad, but I feel like my opening hands are often awkward and am having trouble finding the right balance. Power balance is a slight issue.
- The first variation I made was Rakano, but key pieces were missing: Annihilate, Sabo, Rooftop Vigilante.
- The goal is to hopefully get enough quickdraw/deadly units so they'd essentially be unblockable. Oni-quartermaster provides gas to the deck and Steady Marshal and First-Shot Rioter come in with weapons to get the combo card draw with the oni immediately.
- Stonepowder is a late addition and I have yet to actually see how he fairs.

My Ideas
Hellfire Oni
- Like it, but I feel it may be too greedy and expensive.
Smuggler's Stash
- Could be valuable, but if I get harsh ruled and immediately follow up with this, I'm still probably going to lose.
Sword of Icaria
- Because its a relic weapon/removal.
Valkyrie Cadet
- Would be the deck's bomb. Unfortunately when I ran it in my former rakano version, it's very soft to removal and scarily easy to get 2 for 1'ed which is backbreaking. Still though, I'm ever hopeful this could find a place.

Current Results
- After testing, I managed to get a record of 9-9 (in casual). I want to prove that one does not need to stack their deck with expensive to craft rares/legendaries to have a solid win rate (obviously it helps) and could practically start winning online matches almost right away.
- Any advice or recommendations are very much appreciated.
