I was in D3 this morning and realized I only had a day to ladder up to Masters this month.
This deck allowed me to reach masters fairly smoothly in about 3 hours.
Blazing Salvo has proven to be a fairly reliable market card and gives you the chance to optimize your positioning on Turn 3, which is one of the key turns for Skycrag Yetis to gain momentum and remain on the offensive.
Unseal: The obvious answer to Harsh Rule from control decks on Turn 5. Try and have a wide board with 1, 2, and 3-cost units up until Turn 4-5 with 2 Power left to protect them from a board-wipe. If successful, you have a good chance of winning the game in the next two turns.
Entangling Vines: Used to be fairly popular in main, and currently one of the best 2-drop market card via Salvo to curb opponent's momentum if they happen to play aggro. This one helped me several times vs. Even Stonescar
Cauldron Cookbook: The best 2-drop market card for a draw engine via Salvo but if you are relying on draws with a single unit on Turn 4, chances are your game is pretty sour at that point.
I think I never used Elyn's Favor and Ice Bolt while laddering D1. Perhaps they could be replaced but I would keep Ice Bolt in case you need to move at fat endurance unit like Sandstorm Titan.
Good luck,
