My main of this deck is as follows:
Affinity
Dark Depths
Burn
Enchantress
Nic Fit
RUG
Affinity was a washout in my favor both games. I didn't really put anything of note down other than in game 2 I countered his Phyrexian Revoker which was most likely going to name Grindstone.
Dark Depths was a fun matchup. Game 1 I took my time and didn't combo until turn 5 because I wasn't sure what his deck even was, at first. I saw the Hexmage come out on his fourth turn and figured I'd be safe, lol. Game 2 I cast a turn 1 Grindstone and a Mox Opal , he sat out a t1 Pithing Needle naming Grindstone, and then I dropped a Pithing Needle naming Vampire Hexmage on my following turn (I sided in Blood Moon but never saw it). Two Welders bit a Innocent Blood and a Go for the Throat, but I managed to drop a Painter, Red Elemental Blast the Needle and activate the Grindstone all in the same turn (thanks to a Ancient Tomb, Mox Opal and three other lands).
The burn matchup was kind of hellish. I won game 1 at 2 life because he ran out of cards in hand before dropping me to zero. Game 2 I was stomped due to multiple Smash to Smithereens, game 3 I won by the skin of my ass by countering 2 Price of Progress and a Fireblast with Spell Pierces and a Force. I'm fairly certain he thought it was A-OK to be Fireblast because it wasn't until game 3 that I even drew a Force of Will against him, so after I tapped out and made him sacrifice his only two lands he scooped, showing me 2 more Fireblasts in hand while I had a Welder in play and a Painter/Grindstone in the graveyard at 7.
In all honesty, had it not been for his bad luck/better mulliganing I'm certain he would have curbstomped me.
Enchantress was fun. I didn't really have anything sideboarded for it, and I came out game 1 like a champ. In game 1, I kept a 6 card hand with none of my combo pieces, stuck a Goblin Welder and landed a second turn Intuition off of Mox Opal, Great Furnace and Seat of the Synod. I won shortly thereafter, lol. I sided in Truths over Ensnaring Bridge.
Game 2 I mulligan'ed to 5 and kept a similar hand (Grindstone in the place of Brainstorm), but he laid out a very early Ground Seal with me being powerless to stop it. I eventually drew into a Painter via Brainstorm-fetch abuse, but I didn't cast it even though I had the mana to because I was fearing an Oblivion Ring. His next turn? Nevermore naming Painter, Sterling Grove. I scooped, lol.
Game 3, the stars freaking aligned and I got a hand of Grindstone, Red Elemental Blast, Scalding Tarn, Ancient Tomb, Mox Opal, Brainstorm and Great Furnace. T1 Furnace, Grindstone, Opal and then Brainstorm during his turn got me my Painter. T2, Painter naming blue off Ancient Tomb. He drew, went, "Stony Silence?" I said, "It resolves" and he breathed an audible sigh of relief. I then cast Red Elemental Blast to destroy the Stony Silence and he went, "That was a dick move making me think that I bought me some time, but GG." I was originally intending to shuffle my library with the Tarn to get rid of the Red Elemental Blast, but seeing the Servant meant the Blast wasn't dead so I just played it like a bad player and didn't shuffle lol.
Nic Fit was uneventful each game. In game 1, I recognized it immediately when he played Veteran Explorer on turn 1, so I just kept to myself, playing nothing but Goblin Welder. He let me keep it, and I'm guessing he didn't know what to name with Therapy, but I did an EoT Intuition for Mox, Painter and Grindstone, brought the Grindstone in at the expense of my Great Furnace, then cast the Mox on my turn, tapped it, Weldered it for Painter, activated the Grindstone and he went GG.
In game 2, I drew two Brainstorm so even though he stripped my hand of Painter and Grindstone, he couldn't keep me off my Intuition or Welders. Green Sun's Zenith at 2, Maelstrom Pulse and Pernicious Deed with one mana open all met a Spell Pierce or Force and I swapped my pieces right into play. Again, never drew into Blood Moon. I thought this matchup was going to be a lot harder than it was, but I think I lucked out and the player was the problem, not the deck.
RUG was a tremendous pain in the ass. Game 1 I lost, hands down, thanks to forced Surgical Extraction. Game 2, I forced a Blood Moon to resolve on the third turn with his only creatures being Scavenging Ooze, Birds and Hierarch (and he had already used two fetch). I combo'd out eventually and won, only eating a Fire and Lightning Bolt thereafter. Game 3 I got an amazing starting hand, Grindstone ate an Extraction after it was hit by a Pridemage, but I fetch a Wurmcoil off an EoT Intuition, stick it and slap a Blood Moon the following turn, my opponent then scooped because he had a Natural Order in hand and that was his last outlet to win once the Coil dropped. He spent all of his resources trying to Extraction my Grindstone, and I always had 1 mana open so Daze didn't mean a thing, lol. Talk about lucky
I realize I got lucky almost every one of my games, but it felt good, yo. Ensnaring Bridge seemed like a much better idea on the drawing board, but in the few games I landed it, it was so underwhelming that I didn't even take note of it (it really was just for Emrakul and Progenitus, but none of those even played).
