I was on Painter.

Round 1: Eric Campusano 0-2 – Blowout

He gets an early big Jace both games, I was never really in either.

Game 1 I think he took my Grindstone with Dack to actually seal the deal, but it was a blowout.

Game 2 I was looking at a nice turn 2 Blightsteel, but he dropped turn 2 Big Jace so I had to get Grindstone instead and he won from there. We did learn that you can't have a flipped little Jace and a Big Jace out at the same time when the judge came by and noticed the strange game state, but all that flashed back Time Walk did was make it an even bigger blowout, I was nowhere close to winning either game.

Round 2: Bye. Crushed it.

Round 3: Dredge – 2-1 – Amazing match

Game 1: Turn 1 Painter, Turn 2 Grindstone, he Nature's Claims the Painter in response. Turn 3 Painter off the top, activate and win. At some point I REB'd a Bazaar in response to Fatestitcher in order to hamstring his combo.

Game 2: I have a god hand of something like Painter, Grindstone, Mox, Volcanic, REB, Sol Ring, Island. So many lines, I'd be interested to hear what others would have done here. I go mox, volcanic, tap mox for sol ring, he mental missteps. I decide NOT to REB it (saving it to force through my Grindstone, probably a mistake). He goes nuts and ends the turn with 5 zombies and a 10/10 Troll and Therapies my Painter. Turn 2 I draw Grindstone off the top, which means if I had REB'd the misstep and played Painter off my Sol Ring, he would have Therapied away the Grindstone in my hand, and I would have ripped Grindstone off the top and won. So, that decision combined with a classic turn 2 Dredge kill lost me the game, but I don't know what the probabilities really were. I guess against Dredge you probably always just jam it and protect immediately given the time frame.

Game 3: Turn 1 Grafdigger's cage with misstep backup. He EOT chain of vapors my cage, which I do NOT misstep, because after he dredges next turn (a lot of good stuff), I Ravenous Trap with Narcomoeba trigger on the stack. I replay Cage, and we grind it out for a long time with quite a few duels of Claim/CoV/Misstep/Therapy. Near the end, I draw my second Grindstone, he CoVs my Grindstone in play, which I allow, then he Therapies. Luckily, I still had one Mana Drain in the deck and could Drain the Therapy. I finally end it all on turn 3 of turns with two Grindstone activations WITHOUT Painter in play, one hitting Narcomoeba and CoV to double down, to take him to 0 cards.

Round 4: Dustin on Doomsday – 2-0
Game 1: Turn 3 Doomsday. REB the Lab Man in response to Ancestral with Force and Misstep backup.
Game 2: Turn 3 Doomsday. REB the Lab Man in response to Ancestral with Force backup. There was some confusion here over whether he had made a land drop on his fundamental turn. We sort of agreed he already had, which meant he had to expend a Force on my Demonic Tutor (which would have just gotten another Force for me). If he had been able to make another land drop, he could have won on his turn with an extra Force for my REB.

Round 5: ID with Eliot, as detailed above.

Top 8: Ryan Reynolds on Null Rod Landstill – 2-0
Game 1: He plays Faerie Conclave. I Mox, Volcanic Island, Lotus, Tinker Blightsteel with REB backup.
Game 2: He drops an early Null Rod, I'm trying to set up a sick Painter, REB the Null Rod, Grindstone type of victory, but then I just ripped Tinker off the top and Blightsteel wins. Tinker is broken.
These were two pretty non-interactive crappy games for him for sure.

Split top 4.

Great time. I'm looking forward to the next event!

Piggybacking on this question, why Magus over Blood Moon? Seems like there are more Lightning Bolts, Fire/Ices, Dismembers, Sudden Shocks and Swords to Plowshares than Nature's Claims and Wear/Tears, and Abrupt Decay hits both. It also triggers Oath. Do you just need a beater?

First time playing shops, actually, so I netdecked your Black Magic Invitational list for sure and it felt great. I went with the 2/2 Cavern/Factory split given I was not qualified to make the hard decisions and Factory actually did more work for me than Cavern did, but it's a very small sample size. I never saw Batterskull. MVP Triskelion killed 4 Mentors and 4 Tokens throughout the day, which was the nuts.

Beat UWR Mentor – 1 classic Shops blowout win and 1 good grindy win
Lost to UW Stoneforge 2-1 – 1 bad keep, 1 mull to 5 loss, and one classic shops blowout win
Beat FoW Dredge – 1 classic Dredge mull to oblivion win with a Wasteland for when he actually drew the Bazaar on turn 5, then game 2 Forgemaster -> Metamorphed a Marit Lage token for the block, swing back win.
Beat UBR Welder/Dack/Notion Thief – 1 blowout win and 1 grindy win (Revoker on Dack, Needle on Welder, otherwise that would have devolved quickly).
ID with Rector Gifts – 1 grindy win, 1 turn 1 Trinisphere into no lands for the rest of the game and a hand full of Lodestones and Tangle Wires loss, and 1 blowout loss

Heartbreaker loss in top 8 to the same UWR Mentor. Again, 1 Shops blowout win, 1 grindy loss to 5 8/8 monks and a 9/9 mentor or something. Final play of a grindfest game 3 (enshrined above) was the choice between the "safe" play of Sphere of Resistance vs. the win or lose play of jamming Sundering Titan. Went with Sphere since I assumed 2 DTTs would have gotten him a Force, and got blown out with Hurkyl's -> Ingot Chewer -> Wear/Tear -> attack for 8 with 2 Monk tokens. Turns out he didn't have the Force and Titan would have gotten there with a Lodestone Golem, Sphere, and Chalice for 1 out. Still trying to decide whether it was the right expected value play, or a total bonehead play (likely the latter, as BC disapproved of my decision), but that's what I get for playing a new deck every tournament.

Amazingly fun as always, thank you to everyone who attended. I would strongly support doing these more than 4 times per year.

Suppose i have one Golgari Grave Troll in my graveyard and no other dredgers. I activate Bazaar. For the first draw, i choose to dredge the grave troll, and in doing so, a stinkweed imp is put into my graveyard. Can i use that Stinkweed Imp's dredge for the second draw off Bazaar or, since it wasn't in my graveyard at the time i activated Bazaar, can i not?

Forgive me if I'm blind but is DSC the only win condition? I'm just trying to figure out the deck.

What about Furystoke Giant as a Dread Return target?
 
Flame-kin requires sacrificing creatures pre-combat, but with furystoke you can sac them post-combat. Due to my lack of experience with the deck, I can't tell whether the extra combat damage from the 3 sac'd creatures outweighs the benefit of Flame-kin, but it's just an idea.

how about Ground Seal to keep Welders offline?
