Nice deck, but I have some recommendations for you.

• In general, try to run 2x of most cards. This makes your deck more consistent and also improves your mulligan (if you mulligan one, you won't draw the other).
• Drop both ramshackle and get a second enduring shield and blade of styx. These are both a lot more mana efficient.
• If you have 2x warmonger smiths, definitely run them both. Amazing card.

Best of luck!
