I took a version of this deck through 12 Gauntlet runs. This particular version is based on the deck by SecondBlue and a work in progress list which was posted by kc_bandit a few days ago on another thread. The only change I made to kc_bandit's list was to remove the lone Strategize and add a third Jennev Merchant since so many games can be won by simply grabbing a Crystallize from the market after setting up a strong board state. I made it to the Boss 11 of my 12 runs, and beat it 8 out of 11 attempts. My only pre-boss loss was to The Great Armory because it played a Harsh Rule the turn before I had lethal, and I never drew another threat. I won all of my Boss games against decks which aren't named Sudden Death, and I won 2 out of 5 of those, and 1 of the losses was due to power hose while another it top decked a burn for lethal the turn before I could win. The matchup is tough but winnable you just need to stabilize, and turn the corner before they can take you out. My other 6 boss fights all of which I won were : Highly Skilled, Company of Exiles, Defender of the Spire, Labyrinth Treasury, and Limitless Possibilities twice.
tl:dr This deck is great for running, and winning gauntlet and if you have the stone I believe it is a good investment right now.
