Pale Blue Beatdown

Look, I've crafted 4 copies of Cast Iron Furnace and I won't stop until I make a good deck out of it.

We got some beefy bois (Veteran Mercenary, Wasteland Broker, Prism Golem) that reward turn one Tempting Offer like crazy.

We also have a small discard package (Gustrider, Lightning Sprite, Icy Gaze, Jotun Hurler) that is used to dump low tempo colorless cards such as Seek Answers and Beseech the Throne alongside some colorless power into the void to get the threshold of Cast Iron Furnace quickly, while letting us dig into the deck to find Furnace or Petition.
I've no clue what to put in the market though.

Edit: More discard stuff
