I went 4-0 today at Gamer's Gauntlet with GW Sphere Lands - a 9 player tournament. Won $55 store credit. It was essentially Kurt Spiess's SGC Con list with a few tweaks, and I loved playing it.

(8/19/23)
3rd place out of 17 players at Gamer's Gauntlet Monthly Legacy. 3-1-1 record, for $40 store credit. I ran the list with 2x Crucible main, no Sylvan Library, and Haywire Mite/Containment Priest in the sideboard. Added Thorn of Amethyst to the sideboard as the 5th Sphere effect after Mind's Desire was unbanned.

Match 1: High Tide combo (2-0) Colin Wu
  Game 1 he FOW'd my first Sphere, and then I landed an early Sphere of Resistance on turn 2.
  I hit Pithing Needle on Lorien Revealed, because I didn't see Candelabras yet.. He attempted to combo under the Sphere, using Candelabra got up to 13 mana but it wasn't enough and constructs won me the game.
  Game 2 I made a Marit Lage token which he bounced with Snap. Ultimately, I landed 2 Spheres and won with constructs.

Match 2 - Red/White Initiative Eorlingas (0-2) Phil Williams
  Game 1, Phil landed a Magus of the Moon and I had no maindeck answers. He played Forth Eorlingas and quickly overtook my constructs.
  Game 2 - I answered his Fable of the Mirror-Breaker with a Boseiju, and next turn he played Caves of Chaos Adventurer. I had STP for the Adventurer, but he followed up with a Forth Eorlingas. Construct tokens could not keep up, since I had been playing to tax his mana and his Chrome Mox, Simian Spirit Guides, Sol lands plan was too fast.

Match 3 - Izzet Only Hour of Devastation / bargain bin brew (2-1) Giuseppe; he was joining a friend and brewed an unsleeved deck using only Hour of Devastation set cards. Still managed to take a game off me.
  Game 1 - I got a Sphere down and Wasted a few deserts that he played. I made a marit lage and he unsummoned it. I made very large construct tokens and beatdown to win.
  Game 2 - I boarded in Thorn of Amethyst thinking it was a combo deck (I had only seen spells and cantrips). I got Thorn and a Sphere down, and he hit all his land drops and played 3 2-mana 2-power creatures. Eventually, I chump blocked with a construct and had it unsummoned. I found Maze of Ith too late and his creatures closed the game.
  Game 3 - I boarded back in my Blast Zone and Tabernacle. I played Choke, and one Sphere. I started to Rishadan Port all his Islands, while he got a Firebrand Archer out and started to ping. I eventually assembled Dark Depths/Thespian's stage, and used Choke/Wasteland/Rishadan Port to take him off blue mana (unsummon), and fired off a Marit  Lage token for the win.

Match 4 - Reanimator (1-1-1) Jesse/Hawaii
  Game 1 - I kept a hand with Bojuka Bog in it, because it had Sphere and Urza's Saga. They won the die roll and fired off discard and took the sphere. I played a mox diamond  and turn 1 urza's saga. They put Atraxa and Archon of Cruelty into the graveyard on 2 consecutive turns , but I was already forced to play bog. They passed back and I used urza's saga to tutor for graveyard hate, only I had accidentally left the Soul-guide Lantern boarded out with a Choke in its place from last match. This error would cost me the game, because this was the only window to land that permanent. I ended up picking Pithing Needle to turn off Griselbrand. They reanimated Atraxa, and I bounced with Karakas. They landed Archon, and I fended off with Maze of Ith until the next Atraxa and Archon came down - game loss.
  Game 2 - I played two Spheres of Resistance, Jesse played Dauthi Voidwalker for my loams, but I boarded out 3 Loams and 2 Crucible for 2 Faerie Macabre, 2 Containment Priest, and 1 Surgical Extraction. Also brought in Thorn of Amethyst. I started a tutor plan with Urza's Saga but they killed it with Wear/Tear. They played Serenity and cleared my Mox Diamonds and Spheres. I rebuilt with a Urza's Saga construct plan and attacked through the Shadow to win.
  Game 3 - I muliganned looking for turn 0 interaction and did not find it. They muliganed to 6. I played a sphere of resistance. We went to time and were the last ones to play, so all the players were gathered around. I took a big swing to win with an end of turn Marit Lage, but I had miscounted and was 1 mana short because of my 2x Sphere of resistance. an onlooker called out my blunder so I had to make a new play. Made my Marit Lage 1 turn later, but it was  chumped by an Archon, and killed by the next turn reanimating an archon. Ultimately, we got to extra turn 4 on Jesse's turn, they got 2x Archon of Cruelty triggers (1 attack) and an Atraxa into play, putting me to 1 life. They had to pass, and I drew a land and the game ended in a draw.

Match 5 - Reanimator (2-1) Mark McGarry (John's brother from Lansing)
  Game 1 - He mulligan'd to 5 cards but won the die role and was able to land a turn 2 Gristlebrand, drew 14 cards down to 3 life, picked apart my hand with discard, and dropped another creature. I conceded
  Game 2 - He mulligan'd down to 4 cards, I played a turn 1 Containment Priest, equipped with shadowspear on turn 2 and started to beat down. he Wear/Tear'd my shadowwpear. then got into Urza's Saga constructs and tutored up soul-guide lantern.
He cast Unmask while my hand was Horizon Canopy, Wasteland, Crop Rotation, and Surgical Extraction. There was only Gristlebrand as a reanimator target in the graveyard. I surgical'd his Lotus Petals (2x in the graveyard) mostly to get a look at his hand, and his hand was Archon of Cruelty and Lotus Petal :D  I then used Crop Rotation to hit Bojuka Bog and clear his graveyard, leaving 2 lands for Unmask. I snuck in a Pithing Needle via Urza's Saga tutor, and he missed cracking his Bloodstained Mire so I named it. I beat down with constructs to win.
  Game 3 - he mull'd to 6, then passed his first turn with no plays. I drew and played Exploration/Wasteland. He drew and missed his land drop. I started loaming to assemble Marit Lage. He discards Gristebrand to handsize. I look for graveyard hate. He hits a land, but I land a Sphere and he can't reanimate. I create a Marit Lage and attack for the win. 

1st place ($100) goes to Jason Rosencranz; 2nd place ($75) is Phil Williams; 3rd place ($40) is me; 4th place ($40) is Jesse
