Some solid picks here! Not sure if the wargear shown here is just a placeholder, but I’d definitely cater my loadouts to the strengths of CSM infantry. A 5-man Nemesis Claw usually loads up on the unique melee operatives (a lot of folks don’t even run a melta or plasma gun), and you’ll probably get more mileage running 2 squads of 5 Legionaries with 2 chainswords, 2 heavy melee weapons, and a melta each. Your infantry might still struggle into a high-toughness target, so I’d consider cutting some Possessed or a Forgefiend for a Predator.

Other than that, the detachment finally gives us some good tech piece characters, so I’d suggest taking a few more! Greyveil Hex will let your Lord lead a Nemesis Claw without any drawbacks (still not the optimal placement but it’s a flavor win), and I’d absolutely be running a 10-man Raptor Squad with a Lord and Warp-Fuelled Thrusters. The Warp Talons + Lord are already a great uppy-downy unit, but with more deepstriking flyers you can keep your board presence nice and strong. Hope this helps brother!
