1st Place: Brian Zhu, T’au Empire Army Lists (Tau)
This Tau army list is trying to hit key targets with terrifying precision, flood the mid-board with fast Kroot bodies, and force the opponent into bad trades from the first real engagement onward. There is a lot of pressure packed into this list, but it is not all pointed in the same direction. That is what makes it so good.
Commander Shadowsun
She brings the kind of support that makes the rest of the list feel sharper, especially the heavier hitters that want help converting a big turn into a crippling one. She stands near the parts that matter most, hands out the efficiency boost, and makes the opponent respect the Tau backfield even while the Kroot are already in their face.
Two Commanders in Coldstar Battlesuits
Four fusion blasters mean these models exist to erase something that costs too many points to lose. Tanks, monsters, elite bricks, problem transports, that is the shopping list. The speed of a Coldstar also makes the threat feel unfair because it gets angles that force the opponent to screen carefully or get punished.
Kroot Lone-spear
The lone-spear fits the whole list perfectly because this army wants cheap forward pressure that can also chip in with meaningful support and nuisance play. It helps contest space, threaten odd angles, and make the opponent deal with yet another fast, annoying problem while the main body sets up.
Crisis Sunforge
These two are the point-and-delete bricks. Fusion everywhere means the units are not wasting time plinking wounds off chaff. They are hunting things that are supposed to be durable, making them very mortal and very fast. Backed by a Coldstar, these become one of the nastiest short-range trading tools in the list.
Kroot Carnivores
The Carnivores are here to do exactly what Tau armies always need someone else to do: stand on stuff, screen stuff, and die at the right time so the expensive units do not have to. They are objective holders first, but in a list like this, they are also part of the roadblock package.
Kroot Hounds
Fast, cheap, and annoying, the Hounds exist to gum up movement, screen deep strikes, pressure light objectives, or force awkward charges. They are one of those units that can win a turn without killing much of anything.
In this list, that matters because every inch of space they steal is another inch the fusion teams and Rampagers get to exploit. They are not damage dealers. They are matchup tools, and good players will get plenty of mileage out of them.
Krootox Rampagers
Once they get into the midfield, the opponent cannot casually step onto objectives or leave trading units exposed. They hit hard enough to punish light and medium targets, and there are enough bodies in the unit to make removing them a real job.
This is also one of the army’s best pressure valves. Not every problem needs fusion. Sometimes the answer is just throwing a wall of angry Krootox into the center and daring the opponent to deal with it while the Tau shooting takes apart whatever is behind them.
Pathfinder Teams
This army needs support pieces that help the expensive units hit harder and cleaner, and Pathfinders do that while also contributing useful chip damage through the ion rifles. They are utility units first, but they are not passive.
They also help the army play wider than a normal Tau castle. Instead of everything bunching up behind the heavy suits, the Pathfinders can spread out, claim angles, and make it easier for the list to project threat across multiple lanes.
Riptide Battlesuits are the list’s steady damage anchor
While the fusion teams are all about explosive close-range trades, the Riptide is about repeatable ranged pressure. The ion accelerator gives the army a real answer for elite infantry, medium vehicles, and units that think they are safe hanging back. It is not the flashy assassin piece, but it is one of the most important damage dealers in the army.
It also helps stabilize games where the forward pressure stalls. If the Kroot wave gets bogged down or a fusion drop underperforms, the Riptide still keeps putting real damage into the table. That kind of consistency is why it matters so much here.
Together, the two Riptides are the back-end muscle that keeps the list honest. They punish exposed targets, soften things for the Rampagers, and force the opponent to keep respecting long-range shooting even while the midfield is collapsing into a Kroot brawl.
How This Tau Army List Wins
This army scores by owning the midfield early and forcing the opponent to fight for every objective marker. The Carnivores and Hounds do the cheap action and screening work, the Rampagers bully contested objectives, and the Riptides, plus fusion teams, remove whatever is best at taking those points back. It is less about fancy mission play and more about putting the opponent in a spot where scoring normally becomes a lot harder than it should be.
2nd Place: Charles Burgard, Necrons Army Lists
How This Necrons Army List Wins
This build is pure target overload, and that’s what makes it so nasty. Your opponent isn’t staring down one must-kill threat; they’re staring at multiple C’tan, the Silent King, and a pile of support pieces all demanding attention at the same time.
While they’re busy trying to stop the big monsters from wrecking the mid-board, Szeras and the Reanimators keep the engine humming, the Hexmark chips away where it matters, and the Flayed Ones do the dirty work on objectives.
It’s the kind of list that wins by planting itself in the middle of the table and saying, “Go ahead, try to move me.”
3rd Place: Cory White, Adeptus Custodes Army Lists
How This Adeptus Custodes Army List Wins
This Adeptus Custodes build does not mess around. It leans hard into what the army does best, stacking Custodian Guard across the board and backing them with three Venerable Land Raiders so every lane feels bad to contest.
The Guard squads lock down midfield and bully objectives through sheer toughness, while the Land Raiders add real long-range threat and make the whole army feel faster than a wall of golden infantry has any right to be.
Then the Sisters units chip in with the dirty work, screening, clearing chaff, and handling utility jobs that elite armies usually hate doing. Toss in Draxus for a little extra trickery, and the result is a list that wins by making every trade awkward and every objective fight miserable.
Final Thoughts from us on Warhammer 40k The Dumpster Fire GT Army Lists
The Dumpster Fire GT gave a pretty clean snapshot of what wins games right now. Tau army lists hit with speed and precision, Necrons army lists stacked all their nightmare fuel in one place, and Adpeptus Custodes went full gold brick mode with enough armor to make every objective fight feel like a tax audit.
Each list made life miserable by forcing bad trades and keeping pressure on the table from turn to turn. That is the big takeaway here. Strong lists are not just packing raw damage. They are layering pressure, controlling space, and making every answer feel a little wrong.
If anyone is tuning for the next event, there is plenty to steal from these builds, even without copying them unit-for-unit. Smart support pieces, real board control, and a plan that actually survives contact with the enemy still win games.
Funny how that never goes out of style.
