Defilers and Grizzled Company dominate Warhammer 40k weekend tournaments

Defilers were the surprise, and by the time Robert “TheChirurgeon” Jones closed out Goonhammer’s Traitor Upstartes run on April 25, 2026, they had become one of the weekend’s clearest signals. The final Competitive Innovations installment said it was finishing the week’s look at the top competitive lists, and those lists were crowded with an unusual pair of names: Defilers and Grizzled Company.

That matters because Competitive Innovations is not built as a simple results dump. It tracks what keeps showing up across events, then turns those placings into a read on where the 40k meta is actually moving. Part 1 of the Traitor Upstartes sequence ran on April 22, part 2 followed on April 24, and part 3 landed as the capstone. By the end of that three-day run, the story was no longer just that Chaos lists were winning. It was that players were finding value in threats that look awkward on paper but keep paying off in real games.

Defilers are the biggest tell. Earlier April coverage already had TheChirurgeon testing Death Guard Defilers in practice games, so their appearance in successful lists did not come out of nowhere. What top players seem to be exploiting is the gap between what standard Traitor Space Marine builds can threaten and what these heavier, less familiar choices force opponents to answer. The read from the results is simple: if a list can bring tough, efficient, underestimated threats, it can disrupt plans that are tuned to more common pressure packages.

Grizzled Company is the other half of the story, and it is just as important that this is an Astra Militarum detachment. Goonhammer had already devoted a Detachment Focus to Grizzled Company on December 5, 2025, which gave the build a recent strategy backdrop before it started showing up in results. One concrete example came from Gabriel Yeung, who finished second with Astra Militarum and a Grizzled Company list built around double Dorn, plenty of Kasrkin, and some Scion units. That is a very different kind of pressure from a conventional Chaos shell, but it solves the same tournament problem: it puts durable, high-output pieces on the table that can force bad trades.

The broader read is that this looks more durable than a one-week spike. The mix of Defilers, Grizzled Company, and other underused tools points to a meta still rewarding players who can identify overlooked efficiencies before everyone else copies them. The next round of events will almost certainly bring counters, but for now the advantage belongs to the players who got there first.
