You’re standing across the table from a swarm of Tyranids. Hundreds of tiny, chattering teeth. Then you look down at your side. You’ve got maybe fifteen models. Total. It feels wrong, doesn't it? But that’s the soul of playing a Warhammer 40k Custodes army. You aren't playing a war of attrition; you're playing a game of demi-gods. Honestly, most people get the Adeptus Custodes wrong because they think "low model count" means "easy to play." It's actually the opposite. Every single casualty feels like a physical wound to your soul because that one guy who just died? He was 10% of your total points.
The Ten Thousand are the Emperor's personal guard, and in the current state of the game, they occupy this weird, prestigious niche. They are the ultimate "elite" faction. While a Space Marine is a super-soldier, a Custodian is an artisanal masterpiece of genetic alchemy. In 10th Edition, their role has shifted from being purely unkillable tanks to being surgical instruments of objective control. If you want to push a button and watch an entire unit of Orks evaporate in melee, this is your team.
What Actually Makes a Warhammer 40k Custodes Army Tick
Let’s talk stats. You’re looking at Toughness 6 or 7 across the board for your basic infantry. That’s wild. Most armies dream of having that on their light vehicles. When you field the Adeptus Custodes, you are effectively forcing your opponent to use their heavy anti-tank weaponry just to kill a guy holding a spear. It’s frustrating for them. It’s hilarious for you.
The army thrives on its 2+ armor save and the ubiquitous 4+ invulnerable save. Basically, half the time your opponent successfully hits and wounds you, the Emperor just says "no." But here’s the kicker—you can’t just stand there. 10th Edition is about scoring, and with so few bodies, you have to be incredibly precise about where you stand. If you lose a single objective holder, you might lose the primary mission entirely.
The Shield-Captain Problem
Every new player wants to cram as many characters into their list as possible. Trajann Valoris is a beast, obviously. He ignores modifiers and hits like a freight train. But the real secret sauce of a Warhammer 40k Custodes army is the standard Shield-Captain. Their ability to use a Stratagem for 0CP—even if it’s already been used that phase—is the literal backbone of the faction.
Without those free Stratagems, you run out of gas by Battle Round 3. You need that free "Arcane Genetic Alchemy" or "Vigilance Eternal." If you’re not layering these buffs, your expensive golden boys will die to massed small-arms fire. It’s the "death by a thousand cuts" theory. Even a god dies if you poke him with enough sticks.
Tactical Reality: It’s Not Just About Hitting Hard
Most people assume the Custodes are just a "point and click" army. Move forward, charge, win. Not really. Because you have so few units, your "threat bubbles" are massive but fragile. If you overextend a unit of Allarus Custodians (those are the chunky ones in Terminator armor), you’ve left a massive hole in your backline.
Allarus are actually the MVPs for most competitive players right now. Their "From Golden Light" ability allows them to pop off the table and redeploy. In a game where movement is king, having a 3-man unit of terminators that can teleport to a different objective is basically cheating. It forces your opponent to screen their entire backline, which slows down their advance. You're winning the game before you even roll a die.
The Sisters of Silence Tax
You can’t talk about the Golden Legion without mentioning the ladies in black. The Sisters of Silence are the "cheap" tax you have to pay. They provide the much-needed "chaff" for the army. Prosecutors are great for holding your home objective while your expensive Spears go off to do the actual killing. Plus, in a meta filled with Thousand Sons or Grey Knights, that Psychic Abomination aura is a godsend. It makes Psycastic powers much harder to land. Honestly, if you aren't running at least two small units of Sisters, you're building your Warhammer 40k Custodes army wrong. You need those extra activations.
Why Everyone Is Obsessed With Caladius Grav-Tanks
If you've looked at tournament lists lately, you'll see a recurring theme: the Forge World tax. The Caladius Grav-tank is arguably the best anti-tank platform in the entire game. It’s fast, it’s durable, and the Twin Iliastus Accelerator Cannon shreds heavy armor.
The problem? It’s resin. And it’s expensive.

But from a gameplay perspective, it solves the Custodes' biggest weakness: range. Most of your guys want to be within 24 inches or, ideally, in combat. The Caladius lets you reach out and touch someone from across the board. It forces your opponent to play defensively. Without that long-range threat, an enemy Railgun or Bright Lance will just sit back and pick off your infantry one by one. You need that big gun to keep them honest.
Misconceptions About the "Gold Standard"
A lot of veterans will tell you that the Wardens are better than the standard Guard. They aren't wrong, but they aren't entirely right either. Wardens get that once-per-game 4+ Feel No Pain. It’s incredible for surviving a massive burst of damage. However, standard Custodian Guards allow you to re-roll wound rolls of 1, or full re-rolls if you're on an objective.
In 10th Edition, wounding is harder. Strength vs. Toughness brackets have shifted. Being able to fish for those wounds is often better than just being slightly tankier. If you can’t kill the thing on the point, it doesn't matter how long you live. You're losing the points.
Then there’s the Venatari. The winged custodians. They are "finesse" units in an army of hammers. Most players struggle with them because they fold quickly if caught out of position. But their free rapid ingress? That is a game-changer. Being able to drop down in your opponent's movement phase and then move normally in your turn is the kind of mobility Custodes usually lack.

The Mental Game of Playing the Ten Thousand
Playing a Warhammer 40k Custodes army is a psychological battle. Your opponent sees these terrifying stat lines and gets intimidated. They start over-committing resources to kill one unit. That’s exactly what you want. You want them to waste their entire turn shooting at a unit of 5 Wardens with a 4+ FNP active.
If they spend their whole army's output to kill 400 points of yours, you’re winning. You have to be okay with losing models. The "Iron Mind" is required here. I’ve seen players tilt because they lost two models in one turn. Relax. You’re designed to be the ultimate speed bump.
- Deployment is 90% of the game. If you hide too much, you lose on points. If you show too much, you get shot off the board.
- Layer your buffs. Never leave a unit without a character if you can help it.
- Focus on the mission. Killing is a byproduct of holding the ground.
How to Start Your Collection Without Breaking the Bank
Look, this hobby is expensive. But Custodes are actually one of the "cheapest" armies to get to 2,000 points because the model count is so low.
- Get the Combat Patrol. It’s actually a good value. You get Guard, Sisters, and some Vertus Praetors (the bikes). While bikes aren't the kings of the meta they were in 9th, they are still great for harassing flanks.
- Grab Trajann Valoris. He is non-negotiable. His "Captain-General" ability is a literal "get out of jail free" card for your most important unit.
- Invest in Allarus Terminators. Buy at least two boxes. You can run them as small squads of two to maximize your board presence and teleportation shenanigans.
- Consider one Forge World piece. If you’re serious about winning, the Caladius Grav-tank is the gold standard. If that’s too pricey, look into the Land Raider. It’s not quite as efficient, but it gives you that much-needed lascannon fire.
The Warhammer 40k Custodes army is in a healthy spot. They aren't the "broken" army they once were, but they are a "gatekeeper" faction. If your opponent's list isn't efficient, you will steamroll them. If you play your cards right and manage your limited resources with the precision of a surgeon, you’ll find that quality always beats quantity.
Keep your spears sharp and your armor polished. The Emperor expects nothing less.
Your Immediate Action Plan
Start by playing a 1,000-point game. It teaches you the value of every single model better than a 2,000-point game ever will. Focus on mastering the "Slayers of Nightmares" Stratagem—it's your best tool against big monsters and vehicles. Once you can win at 1k with only 10 models on the board, you’re ready to lead the full Ten Thousand.
