Notable Exclusions

Hellkite Tyrant: The thought of my opponent cloning or stealing it scares me. Bribery's prevalence in my meta is enough to exclude him.

Hellkite Igniter: I have tried it out before, and I found that after I payed his summoning cost I didn't have enough mana left over to swing for lethal.

Bosh, Iron Golem: I think his activated ability costs too much and does too little. Remember, I'm trying to win by going infinite.

Caged Sun: I used to have it in the deck, but I found out that it was outclassed by my other choices for reanimation targets.

Gamble, Metalworker, Grim Monolith, and Crucible of Worlds: I don't want to throw the money at these pieces yet.

Burnished Hart: I don't want to dedicate turns 3 and 4 to getting two mountains.

Valakut, the Molten Pinnacle: It enters tapped. I'll only make an exception for Flamekin Village because it lets Kuldotha Forgemaster and Goblin Welder do their dirty work immediately.

Trading Post: I think it's too expensive and slow for what I'm trying to do with this deck.
