Warhammer 40K: Adeptus Mechanicus Crowned Champions at the World Championships of Warhammer

Adeptus Mechanicus are crowned champions at the World Championships of Warhammer. Here is a look at the winning list, key decisions, and meta implications for Warhammer 40K.

After months of qualifying events, roster building, and intense preparation, we officially have a new champion at one of the biggest competitive events in Warhammer 40K — the World Championships of Warhammer.

Richard Siegler, piloting Adeptus Mechanicus, secured the title with an impressive victory over Liam VSL on Aeldari in a tightly contested final matchup that showcased two very different approaches to the game.

A Clash of Styles and Player Profiles

On paper, this matchup looked like a showdown between two players with very different trajectories coming into the event. Liam VSL is widely regarded as one of the strongest players in the world. While ITC ranking is not a perfect measurement of competitive skill, his #32 ranking reflects a high level of consistency — and his recent win at the London Grand Tournament reaffirmed that reputation.

Siegler, by comparison, came into the event with an ITC rank of 411. That ranking undersells him a bit — Siegler is a two-time ITC Champion and one of the most technically gifted players in the competitive scene. But it does highlight the difference in hype and expectations heading into the final table.

Once the dice hit the table though, rankings and reputation take a back seat. Siegler played precise, disciplined Warhammer, navigating critical trades and pressure angles with a level of strategic clarity that kept Aeldari’s board control and scoring options under constant constraint. By the end, the result was clear: Adeptus Mechanicus were the better army on the day, and Siegler executed the gameplan needed to win.

Why This Result Matters

The outcome itself isn’t shocking — both Aeldari and Adeptus Mechanicus are currently among the top-performing factions in the game. However, they are not strong in the same way.

• Aeldari excel through efficiency, psychic support, and movement control.

• Adeptus Mechanicus leverage layered buffs, overlapping synergies, and surgical pressure.

For the last few months, Adeptus Mechanicus have been trending upward. Points reductions, rules tuning, and a clearer internal balance have dramatically increased the faction’s competitive viability. Siegler’s list showcased that evolution — taking units that were once considered marginal and elevating them through synergy, sequencing, and board-state awareness.

This win marks Ad Mech’s strongest high-profile finish in the current meta cycle and is likely to have a ripple effect across the global competitive scene.

Expect:

• Increased experimentation with Adeptus Mechanicus list archetypes

• A rise in metal cogboys on top tables in local and GT play

• Counter-tech considerations emerging in list construction across factions

It’s not just that AdMech won — it’s how they won: with clean fundamentals and repeatable game patterns, not gimmicks.

Both Finalists Showcased Elite-Level Play

While Siegler ultimately took the title, both players demonstrated why they consistently appear in deep tournament runs. The game was a showcase of:

• Precise scoring decisions

• Patience in tempo trading

• Calculated unit commitment

• Strong understanding of secondary objectives

There were no gimmicks. No accidental blowouts. This was Warhammer played at the highest level.

Conclusion

This result reinforces what many competitive players suspected: Adeptus Mechanicus are now fully established as a top-tier faction in Warhammer 40K, and they are here to stay — at least for the current balance window.

Siegler’s win is not just a single tournament result. It is a proof of concept for where the faction stands and how it can perform in the hands of a disciplined pilot.

Both players represented their factions — and the competitive community — incredibly well. Expect to see more AdMech on tournament tables, more variation in list building, and more discussion about the evolving shape of the meta in the weeks to come.
